aFe Silver Bullet Throttle Body Spacer Kit AFE46-31006 for BMW V8 4.4L and 4.8L

Silver Bullet throttle body spacers create turbulence in the air flow at the point just prior entry into the engine increasing horsepower, torque and improving throttle response and fuel efficiency. Silver Bullet throttle body spacers are constructed out of durable T-6061 billet aluminum and using a unique serrated/helix entry to create turbulence at the manifold while eliminating the annoying whistle found in other helix only throttle spacers.

Improve airflow and throttle response with the aFe Silver Bullet Throttle Body Spacer Kit, part number AFE46-31006. Designed for select BMW applications equipped with N62 V8 engines, this spacer uses a precision-engineered serrated and helix entry to create controlled turbulence as air enters the intake manifold. The design helps increase air volume and may improve horsepower, torque, throttle response, and fuel efficiency while avoiding the excessive whistle associated with helix-only throttle body spacers.

Manufactured from durable T-6061 billet aluminum, the Silver Bullet spacer is precision machined for reliable performance and long-term service. Its special helix design is compatible with aFe intake systems and is engineered to integrate with the factory intake configuration on supported vehicles. The kit includes the throttle body spacer and installation hardware required for installation. A two-year limited warranty provides additional product support.

Application coverage includes select BMW 545i, 550i, 645Ci, 650i, 750i, and X5 models with 4.4L or 4.8L N62 V8 engines. Confirm the vehicle, engine, and intake configuration before ordering. Listed fitment includes 2004-2005 BMW 645Ci, 2006-2010 BMW 550i, 2006-2007 BMW 650i, and selected BMW X5 E53 applications from 2006-2008. This product is EPA compliant and carries CARB Executive Order D-550-11 where applicable. California emissions requirements may vary by vehicle and installation location.
