Using a serrated/helix design, this spacer creates turbulence in the air flow at the point just prior entry into the engine optimizing the combustion cycle. This turbulence helps the air/fuel charge burn completely providing increased horsepower, torque and improved throttle response for your 2000-06 BMW X5 (E53) V8-4.4/4.6L / 04-05 545i (E60) / 04-05 645i (E63/64). This spacer works with the OE and aFe Power cold air intake systems.
Serrated/Helix Design: The Serrated/Helix combination design creates intake turbulence in the combustion chamber. This turbulence breaks up the fuel which creates a more complete combustion cycle increasing horsepower, torque and improving throttle response. The Serrated/Helix combination design also reduces intake whistle that occurs with other Helix only designs.
T-6061 Billet Aluminum Construction: All Silver Bullet Throttle Body Spacers are precision machined from T-6061 billet aluminum for light weight, high strength and perfect fit and finish.
Longer Intake Track: Adding a Silver Bullet Throttle Body spacer lengthens the intake track which helps increase intake air speed increasing performance and improved throttle response.
