The E92 335i has become the BMW to tune. It has become synonymous with making big horsepower with relatively easy modifications. There have been countless N54 Powered project cars built all over the world. Our E92 335i came to us back in early 2007 soon after the E92 chassis was introduced to the US market. We were extremely excited to be the first North American tuner to begin research and development on the new twin turbo inline six three liter engine.

| Additional 335i Engine Upgrades | |
| 335i Cobb AccessPort Programmer If you do only one upgrade to your 335i it had better be this. This is your "all-in-one" programming tool for 335i performance upgrades. Not only can it flash your 335i ECU with new performance files but it also works as a diagnostic code reader, live data display, and data logger. The Cobb AP plugs into the car's OBD port in the footwell. You can choose to leave it plugged in and on the included cradle or unplug it after performing your software upgrade or diagnostic work. When plugged in the ultra clear display can show 6 additional gauge readings - pedal position, battery voltage, coolant temp, intake air temp, ignition timing, boost, and more. Performance maps are available for nearly all of the popular bolt-on upgrades for the 335i. See the tuning stages above for an idea of the tuning potential of the N54 with the Cobb AccessPort.

| 335i aFe Dual Cone Intake This sealed cold air intake system is engineered to let maximum air in while keeping engine heat out. Featuring two uniquely shaped molded intake ducts that replaces the single stock intake tract, this intake system smoothly directs increased air flow for improved volumetric efficiency and maximum performance. So effective is the design that Intake Air Temperature (IAT) at normal running speeds is 11 degrees lower than the factory intake. Complementing the dual intake tract are two Dynamic Air Scoops (D.A.S.) that further direct air into the engine. Easily accessible with a satin black powdercoated aluminum cover, an washable/reusable conical air filter is enclosed in a molded plastic housing and mounted on a oval intake tube that smoothly supplies maximum air to the twin turbos. The full effect of this system cannot be felt or tested on stationary dyno and can only be fully appreciated on the wide open highway. By removing your stock intake air box, you are removing the most restrictive portion of your 335's intake system, increasing both horse power and torque, improving acceleration as well as throttle response.

| 335i Intake Air Scoops Direct more fresh cool air from your BMW's center/nose grills to your intake, with the aFe D.A.S. (Dynamic Air Scoops). These two "scoops" install behind your front grills to direct more airflow into the factory intake snorkel. These scoops are a direct bolt-in install, and include installation instructions and required hardware for a simple install. When combined with a higher flowing filter kit these scoops help get the maximum benefit of a higher efficiency filter by providing more cool, fresh outside air directly into the intake snorkel. Both the turbo models and the 4.0 V8 models especially need this added air flow for best horsepower and torque. Click here for more info. |

| 335i Chargepipe Upgrade with Blow-Off Valve All of the tuning in the world is only as good as the weakest link. More boost in your 135/335 is great! But you will soon learn that some of the factory hardware is not up to the task of handling that extra pressure. One of the first things to fail and cause a boost leak are the factory boost diverter valves. This allows boost to "leak" out of the intake stream and a loss of power from the engine. This ECS Tuning chargepipe upgrade includes a blow-off valve in place of the factory diverter valves. The BOV is higher quality than the diverter valves and will exit intake air to the outside instead of putting it back through the turbo system (which will reduce strain on the turbos). This aluminum chargepipe is also much more robust than the stock plastic factory pipe and the connection to the throttle body is stronger, eliminating another failure point of the stock pipe.

| 335i Oil Catch Can Oil venting and circulation is a common problem area on the turbocharged N54 and N55 engines. The existing stock system does a very poor job of separating fluid and vapor and this leads to an oily film or even small pools of oil throughout the turbos and intake. We're seeing a lot more 135 and 335 cars with drivability and performance issues because oil has sneaked by the ring seals and is coating the intake piping, intercooler, intake valves, and other critical areas. The problem is worsened with higher boost levels. Oil is excellent for lubricating moving parts but terrible when it gets into the combustion chamber, effectively lowering the octane rating and reducing performance. The oil catch can traps oil as it leaves the valve cover and holds it in a canister. Whatever minimal vapors are left over in the oil is then vented back through the canister and into the intake where it is safe to be burned up in the engine or recirculated back through the system again. At each oil change simply unscrew the canister and empty the trapped oil with your regular used oil. Click here for more info. |

| 335i Wagner Evo I Intercooler Wagner intercoolers are engineered in Germany to be a superior N54/N55 intercooler than the factory part. With 85% more surface area than the factory IC the Wagner-designed kit is much more efficient. And that helps maintain your boost levels and performance! The factory intercooler is quickly overcome with heat and that leads to a loss of boost and performance. The solution is an intercooler with more capacity for cooling and Wagner has chosen the stepped design to maximize the available surface area in the front end. The best feature of this kit is how easy it is to install (the easiest we have used to date). It's a direct bolt-on replacement for your stock intercooler - no removing the bumper or modifying brackets or wrestling with plumbing. Click here for more info. |
|
| 335i COBB Front Mount Intercooler Kit The Cobb Front Mount Intercooler (FMIC) uses an innovative stepped design to maximize the available space in the nose without major modifications for installation. With 60% more surface area than the stock intercooler, the Cobb FMIC delivers much lower intake air temps for more consistent and useable horsepower. Adding any more boost and the stock system is quickly overwhelmed. As the ECU corrects for heat soak you will be losing power, which makes your upgrades worthless. To help maintain boost levels even in the face of elevated turbocharger temperatures, a more efficient intercooler is required. The stepped cooler design uses all of the limited nose area of the E82, E90, and E92 body styles. Cast aluminum end tanks are specially formed to optimize flow (another obstacle for efficiency). Only minor modifications are required for installation and new silicone hoses and clamps are included. Special software is already available direct from Cobb to work with their FMIC via the Cobb Accessport programmer. Click here for more info. |
Radiator - PWR Aluminum - E82 135i, E89 Z4 28i/35i, E9X 335i/xi manual This PWR radiator for the E90/E92 335 and E82 135 is a larger 42mm core (4mm thicker than stock) for additional capacity and bulletproof cooling. It fits in the stock location, with the stock shroud and fan (some plastic trimming may be necessary), maximizing the available space to dedicate to fluid capacity and surface area. Having a greater capacity means less saturation time for the cooling fluid which leads to more consistent engine temperatures, reducing the possibility of limp mode condition and reducing wear and tear on other cooling components such as the water pump and thermostat. If you're looking for the most complete and unbeatable radiator solution for your E9X, this is the best we have seen. Click here for more info. |
| 335i Ignition Coil OK, it's not the sexiest product to put in a catalog but any mention of 335i performance should include new or spare ignition coils. For some reason, ignition coils on BMWs fail often. They are subject to intense heat and vibration and can be contanimated by oil and dirt. A failed ignition coil (or coils) will lead to a misfire, poor performance and fuel economy, and possibly even a limp mode. With a faulty coil the spark plug is not burning the air/fuel mixture properly and that can lead to problems anywhere in the engine and exhaust (including catalytic converters and O2 sensors). Don't let one of these ruin your day and stay on top of your maintenance! At the very least, carry a few of these with you as spares. Click here for more info. |

| 335i Suspension Upgrades | |
| Bilstein PSS10 Coilover Kit for E9X 3 Series The Bilstein PSS10 Suspension provides the ultimate in performance tuning. The fully-adjustable monotube gas shock absorbers offer a selection of TEN precise compression and rebound settings, from comfort to competition. Each setting "clicks" into place, and a labeled indicator lets you know exactly what setting you are on, without any counting of clicks. The front and rear progressive rate springs allow accurate adjustment of the vehicle ride height and center of gravity for the level of performance you seek. Click here for more info. |

Front and Rear Sway Bar Upgrades for E9X 3-series Larger sway bars are designed for drivers who desire improved handling without lowering or affecting ride quality. H&R and Turner Sway Bars increase your suspension's roll stiffness ÃÂ its resistance to bodyroll in turns ÃÂ while maintaining ride comfort and dramatically increasing cornering control, lateral stability, and grip. Sway bars act as levers on the suspension and the larger the bar the more force and control it can apply to the suspension. These swaybars have been carefully designed for the E9X non-M chassis to reduce bodyroll and keep the tires in contact with the pavement. A sway bar upgrade is not just for track or autocross - this is an improvement you will feel on your favorite back roads and on/off ramps. Click here for more info. |

| Solid Rear Subframe Mounts for E9X 3-series A BMW's rear subframe is the heart of the suspension. When the subframe moves, so do all the suspension mounting points. Factor in a lot of additional torque from a tuned motor and the stock subframe mounts become a big weak spot.. Replacing the stock rubber bushings with a stiffer mount limits both drivetrain and suspension movement, eliminating the unwanted changes in alignment and keeping your BMW's setup the way it should be. These solid aluminum mounts are from our racing program but we have had great success using them in highly tuned street cars as well. Since they are a solid mount there is no play or deflection even under extreme loads. And they last forever! Even BMW has seen the benefits of solid mounts and the F10 M5 and F8X M3/M4 come from the factory with them. If you're not interested in solid aluminum we also offer them in Delrin, ultra-stiff rubber, and the stock M3 mounts. All are upgrades over the stock 335i mounts. If you're upgrading the rear sway bar this is the perfect time for subframe mounts as the subframe must be lowered or removed anyway. Click here for more info. We have other stock and performance mounts for the 335i! Click here for more 335 mounts. |

M3 Front Upper+Lower Control Arm Upgrade - Left and Right - E82, E9X The front upper and lower control arms from the E9X M3 are a direct bolt-in replacement upgrade for the stock parts on the non-M E90/E91/E92/E93 3-series and E82/E88 1-series. With the M3 components the fluid-filled bushings of the standard suspension are replaced with solid rubber cores or a sealed monoball-joint, making the suspension stiffer, more responsive, and longer lasting. Click here for more info. |
|
M3 Rear Guide Rod Upgrade - Left and Right - E82, E9x These M3 rear guide rod arms are an upgrade for the non-M cars. The stock non-M arms are made from sheetmetal spot welded together at the ends. The arm tends to flex and bend under even moderate cornering loads. Factor in gripper tires and more torque and this arm is inadequate for stability and consistent handling. The M3 arms are one piece of aluminum offering greater strength and with a sealed monoball inner bushing that allows the arm to rotate (instead of twisting). Click here for more info. |

M3 Rear Upper Link Arm Upgrade - Left and Right - E82, E9x These M3 rear upper link arms are an upgrade for the non-M cars. The stock non-M arms are made from sheetmetal and tends to flex and bend under even moderate cornering loads. Factor in gripper tires and more torque and this arm is inadequate for stability and consistent handling. The M3 arms are one piece of aluminum offering greater strength and with a sealed monoball inner bushing that allows the arm to rotate (instead of twisting). Click here for more info. |

| 335i Brake Pads for Street Use We offer multiple types of brake pads to suit your driving needs and expectations. For the street we have OEM replacement, low dust, and performance pads for the E9X 335i. We offer a complete selection so you can get just the right pad for the type of driving you do: daily commuting, sporty or aggressive, back road carving, and more. Street pads should be user-friendly with no noise or vibration. They need to work right away, even at cold temperatures. Street pads generally trade high temperature performance for low temperature performance, which makes them work excellent in street situations but generally do not hold up well over continued track use. See below for brake pads for mixed street/track use and all-out track/HPDE and racing use. Click here for more info. |
|
| 335i Brake Pads for Mixed Street/Track and Autocross Use "Mixed use" street/track pads are also known as beginner's pads. They are intended for rookie and first-time track drivers who know that their normal street pads will not hold up in prolonged track environments. Using a pad with higher metallic and/or ceramic content will improve its resistance to fade at higher temperatures. Unlike strictly-street pads, mixed-use pads need some heat in them to work effectively. Therefore, they are not the best for regular street use. Metallic pads also tend to squeal and produce large amounts of dust. On the other hand, these are not all-out race pads and some fade on the track may occur. Street-track pads will be fairly easy on rotors and have long life when kept within their operating temps. These generally also work grea | |
