Enhance your BMW's engine performance with the aFe Silver Bullet Throttle Body Spacer Kit designed specifically for BMW 5 Series (E60) models from 2004 to 2010 and select V8 models including the 545i, 550i, 645Ci, 650i, and 750i. Crafted from durable T-6061 billet aluminum, this spacer features a unique serrated/helix entry that creates turbulence in the airflow just before it enters the engine, resulting in increased horsepower and torque. Additionally, it improves throttle response and fuel efficiency by optimizing airflow dynamics. The precision-engineered design effectively eliminates the common whistling noise associated with other helix-only spacers, ensuring a smoother driving experience. This product is compatible with V8 4.4L and 4.8L engines and is compliant with EPA standards, making it a reliable upgrade for your vehicle.
The installation of the Silver Bullet spacer is straightforward and provides a noticeable boost in engine responsiveness. By improving airflow turbulence at the throttle body, it enhances combustion efficiency, leading to better acceleration and overall engine performance. The robust construction from billet aluminum ensures longevity and resistance to engine heat, maintaining optimal performance over time. Whether you're looking to improve daily driving or seeking a performance edge for spirited driving, this spacer provides an effective solution without compromising vehicle reliability.
This product adheres to all necessary environmental and safety standards, including Prop 65 compliance, and is suitable for use on a wide range of BMW V8 models within the specified years. The spacer's design ensures a seamless fit, making it an excellent choice for enthusiasts aiming to maximize their vehicle's potential with minimal installation effort.
