Product Details
For vehicles with a production date up to 09/1998 and Bosch alternator
"Intake, exhaust, pulleys, tune" - long the standard for performance on naturally aspirated BMW, these four simple modifications offer some of the best bang for your buck when it comes to modifying your BMW. Whether looking for your first modification, completing your daily driver or weekend warrior, or starting with a stock car with high aspirations, focusing on these four systems (intake, exhaust, pulleys, and software) offer good gains with little to no compromise.
Intake - Allow your engine to breathe more easily by reducing intake turbulence and introducing cooler air will improve power output and throttle response - with the added benefit of some additional sexy intake volume. A leader in BMW intakes, aFe intakes offer both a heat shield and blow-molded intake tubes - Pro 5R filters are reuseable, with cleanable oiled filters. Expect 5 horsepower from a performance intake on the 528i.
Exhaust - The other end of the equation from the intake, exhaust not only impacts power production, but also is the voice of your BMW. Enthusiasts looking for an impressive bang-for-their-buck in exhausts will frequently remove the center butterfly resonator, allowing for some additional volume and less flow turbulance with the addition of notable weight savings. Supersprint offers a cut-and-bolt-on solution in pre-bent stainless steel. Great for the daily driver - if you're looking for a screamer, add a Supersprint muffler, too.
Pulleys - Eliminating parasitic loss equals a quicker revving engine with more available horsepower. Turner Motorsport Power Pulleys deliver up to 11 "freed" horsepower and are available for vehicles with Bosch and Valeo alternators. No downside.
Tune - Shark Injector performance software is a super-simple tuning solution that does not require a computer or any vehicle downtime to utilize. Developed on hours of dyno time, BMW tuning pioneer Jim Conforti crafted ideal software for the M52 engine. Simply plug the provided OBDII Shark Injector into your vehicle, push the button, and in minutes have a vehicle with +15 horsepower, +9 lb/ft torque, with better throttle response and a 7,000 rev limit. Delivers an all-around improved driving experience.

Don't run around piecing together your ideal performance machine - let ECS be your partner in building the car of your dreams. Looking to build a wilder ride?
