Gain up to 10+whp along with terrific sound!
Finally, an affordable intake system worthy of your S55 M3 and M4! The BMS Elite S55 Performance Intake retains everything that’s good about the OEM intake including the cold air ducting and light weight heat shielding airbox bottom, but replaces the top end of the intake with higher flow ducting and quality inverted cone air filters to match.
During dyno testing the BMS Elite S55 Performance Intake performed the same or better than other S55 intakes tested posting gains of up to 10+ horsepower to the wheels at 25psi+ boost levels. Note the OEM S55 air intake flows very well from the factory so gains are mostly present at higher boost levels and higher RPM where airflow requirements are highest. In addition to freeing up some power turbo spool speed was improved, and there is an incredible sound improvement. You’ll finally be able to hear your turbo spooling!
Installation is easy and fully reversible. Proprietary high flow filters can be cleaned every 15-20k miles using a S&B cleaning kit and will last the life of the car. BMS intake temperature testing found no significant difference from the factory intake during both sustained cruise and full throttle operation.
