Gruppe M - Ram Air System - BMW E89 Z4 sDrive35i
GRP012
Made in Japan, GruppeM Ram Air Intakes epitomize the GruppeM philosophy of attention to detail. By replacing the factory air handling systems, increased airflow streams into the combustion chamber. On the GruppeM intake for the BMW E89 Z4 sDrive35i, the factory ductwork is replaced with heat-shielding carbon fiber with enhanced inlets to capture the maximum amount of air. Lower intake air temperatures carry higher concentrations of oxygen, allowing for more energetic explosions and producing more horsepower and torque. Of course, reliability is never sacrificed -- high-efficiency, high-flow K&N air filter materials prevent contaminants from interfering with proper engine function. Learn More$2,830.00 -
