E9X M3 Power Kit - Stage II (05/08+)

The Hardware of this kit consists of the Macht Schnell E9X M3 Stage 2 Intake Charge Kit.  It's our favorite choice for E9X M cars because it's designed for power! By replacing the restrictive stock filter with a larger, more free-flowing performance filter, the engine is able to breathe more air - and that means more power.

The disruptive accordion-style stock intake elbow that connects the air box to the intake manifold is also replaced. This Macht Schnell replacement Intake Charge Pipe (ICP) has very smooth and glossy interior walls, and it's also 18% larger by volume, so you get considerably more air while eliminating the turbulence and resistance that the stock elbow produces. The ICP is constructed from super-strong polyethylene and has a textured exterior that perfectly matches the texture of the OEM intake manifold for a stock look. Macht Schnell's own Intake Charge Scoops are part of this cost-effective kit, and they help to create a matched combination that provides maximum air delivery to your S65 engine for noticeable power gains.

The Software portion of this kit consists of Epic's custom ECU tuning. Epic tunes are able to provide more usable horsepower and torque outputs by modifying BMW’s dual variable cam timing (VANOS), drive by wire tables, and fuel and ignition maps. Better part-throttle drivability is also obtained.

The vehicle’s top speed governor is removed. Custom software modifications for headers or other modifications are available. Rear O2 sensors monitoring, as well as other emission related items, can be disabled upon request for race cars and/or off-road use only vehicles.

This tune includes the Engine Calibration Interface (ECI) with purchase.

More Hardware to kick it up a notch. Rogue Engineering Power Pulleys for your E9X M3 (thru 04/2008) consists of pulleys that are CNC-machined from 6061-T6, heat-treated aluminum and specially coated with MIL-A-8625 Type III hardcoat anodized finish. Not to be confused with the cosmetic Type II anodized finish, RE's anodizing actually builds a small surface layer on top of the aluminum, preventing wear. This hardcoat anodize not only offers a true protective layer, but it also has a unique jet-black, gloss finish unlike the dark grey of other hardcoat finishes that actually looks brown. This unique finish is standard on all Rogue Engineering pulleys.

Rogue Engineering's power pulley kit effectively reduces the drag on specific pulleys while allowing others to remain at their same efficiency. This kit makes for the perfect blend of daily-driver smoothness with noticeably increased power that's always on tap. Power pulleys don't so much add power as they do to free up existing power that's reduced through drag from accessory pulleys. The RE pulleys are specifically calculated from factory dimensions, so component speeds are safely reduced without any negative effects to their true purpose.

This Rogue Engineering Power Pulley kit benefits all cars, not just those with manual transmissions. Steptronic, SMG, DCT and all-wheel drive cars can also benefit from the newly released power of the pulleys.

Kit Includes: Crank shaft pulley, power steering pulley, new high-quality serpentine belt, and installation manual.

Note: E9X M3 kits use commonly available belts. Replacements can be acquired at most local auto parts stores.
