Free additional power to your M3’s rear wheels without sacrificing or compromising your BMW’s reliability. Machined from 6061-T6 aerospace aluminum, Macht Schnell Performance Underdrive Pulleys are strong as well as lightweight to limit parasitic drag from the accessories within a moderate level for maximum performance on or off the track. After machining and engraving, pulleys are then T3 hard anodized for additional strength, anti-corrosion & wear resistance. Our DualDrive design replaces the Crank Accessory & Power Steering Pulleys, resulting in an additional 9-14 HP and 7-9ft. lbs TQ gain for the M3. Gains are due to a reduction in power required to turn accessories; an increase in accessories lifespan due to lower speed will also result. All factory harmonics/balancing are undisturbed. Macht Schnell Performance Underdrive Pulleys have no negative effect on accessory operation and comes fully equipped with new belts. Already have this kit and need new belts? See T#14491 and T#14489 Performance Underdrive Pulleys Features: DualDrive design allows maximum performance, with minor effect on accessory speed Proper cooling temperatures are retained at proper levels on or off the track Maintains proper alternator speed, allowing sustained levels to sensitive control modules Machined from 6061-T6 aerospace aluminum T3 Hard-Anodized for maximum strength and corrosion/wear resistance No affects to crankshaft dampening or harmonics Simple bolt-on installation

2007-2010 E90/E92/E93 335i N54 Stage 1+ Performance Package
Peak Power Gain*: up to 103hp / 108ft-lbs
+ aFe Pro5R Dual Cone Intake
+ Wagner Front Mount Intercooler
+ Cobb AccessPort programmer


More power = more heat. It's easy to make more power one time but to continue making that power consistently requires careful planning and design. With the additional boost the air entering the engine is also warmer, making the intercooler more important than ever. In testing, the stock BMW intercooler was quickly overwhelmed and cannot keep the intake air cool enough. The engine computer recognizes that and dials back the boost. A more efficient intercooler will keep boost levels up, delivering consistently higher boost levels. The Stage 1+ package includes a Wagner Evo I plug and play intercooler upgrade. We get great feedback from our customers and technicians about the Wagner FMIC - it's a direct bolt in part using all of the factory piping and it offers 85% more surface area than the factory intercooler.

The aFe Dual Cone intake and Cobb Accessport programmer complete the Stage 1+ package. The larger surface area of the aFe cone filters allows more air to enter the engine - creating more power and torque, a richer engine sound, and better throttle response. The kit is supplied complete with aFe Pro5R filters, mounting shield, intake tubes, sealing materials, hardware, and install instructions. The torque increase and sound from the open intake from low-mid RPM is sensational.

The Cobb software tool puts multiple tuning stages in the palm of your hand. Our Stage 1+ package lines up with the Cobb Stage 1 tuning maps for an intake and FMIC (91 or 93+ octane fuel). Simply download the Stage 1+ map from the Cobb website, plug it in, and install. Select different maps for other upgrades, throttle settings, octane ratings, valet mode, or revert back to stock! If you're moving up in Stages simply download a new file from the Cobb website and update your AccessPort programmer! The AccessPort triples as a diagnostic tester/reader and a data logger. It's the most feature-packed programmer on the market today.

We have taken the guesswork out of choosing the best upgrades for the N54 engine. If you follow the upgrade path we have laid out you will have very satisfying and reliable results. The addition of the larger intercooler makes Stage 1 more enjoyable and won't let you down at the track or dragstrip. * Note that peak power gains are quoted remain the same as Stage 1 but the cooler intake air means there is less of a chance the engine computer will cut power from heatsoak.

This item fits the following BMWs:
2007-2010 E90 BMW 335i 335xi 335i xDrive - Sedan
2007-2010 E92 BMW 335i 335is* 335xi 335i xDrive - Coupe
2007-2010 E93 BMW 335i - Convertible
* 335is horsepower gains are lower due to the factory power boost in the "is" package
