The VRSF High Flow Air Intake upgrade for your M3/M4 replaces your restrictive OEM intake with a high flow design. This kit was designed to retain the OEM cold air ducting and eliminates the upper portion of the air intake which has been proven to be incredibly restrictive, especially in the upper RPM range. The result is a gain of up to 14whp in the mid to upper RPM range when increasing boost above OEM levels. Our high flow inverted S&B cleanable filters offer increased flow along with a more aggressive intake sound. This upgrade also offers improved turbo spool as well as an increase in transient response.
We include everything necessary to replace your OEM intake including couplers, clamps and filters. This kit is completely reversible and does not require any permanent modification.
