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

Arqray focuses on the performance, quality and sound of all their exhaust systems. A feature of every Arqray exhaust system is the tube diameter is carefully selected for each and every car depending on the engine's displacement and characteristics. This allows an increase in performance and sound while remaining true to the OEM smoothness that BMW excels at. Arqray torque and power curves are generally flatter and more linear than other exhaust systems. Each exhaust is also tuned to free up the engine's sound while still letting the engine's characteristics shine through. Learn More
