DescriptionAfter relentless testing, GruppeM engineers created a large capacity RAM AIR SYSTEM, also known as cold air intake (CAI), exclusively designed for the BMW F80 M3 making full use of the engine bay drawing in the maximum amount of ambient air available. Designed to lower intake temperatures by channeling ambient air thru an enlarged intake duct increasing horsepower and engine torque throughout the power band delivering a sharp boost in performance from 3,500 ~ 5,500 RPM revealing a truly sporty sound at high rpm producing power, beauty, grace, and elegance with simple bolt-on installation, unsurpassed fitment and finish.
