Enhance your BMW E53 5 Series (2004-2006) with the aFe Silver Bullet Throttle Body Spacer, designed specifically for V8 4.4L and 4.6L engines. Crafted from durable T-6061 billet aluminum, this spacer features a unique serrated and helix entry that creates turbulence in the airflow just before it enters the engine. This turbulence improves airflow efficiency, resulting in increased horsepower, torque, and improved throttle response. Additionally, it enhances fuel efficiency by optimizing air intake dynamics, providing a noticeable performance upgrade without the need for complex modifications.
Installation is straightforward, and the spacer is engineered to eliminate the common whistle sound found in other helix-only spacers, ensuring a quiet and smooth operation. This product is compliant with EPA standards and is not CARB-verified, making it suitable for use in many regions. The design also ensures a perfect fit for BMW models including 2003 to 2009 5 Series (E60), 6 Series (E63/64), and other compatible models. The aFe Silver Bullet Throttle Body Spacer is a reliable upgrade to help maximize your vehicle's performance and responsiveness.
Built with precision and quality, this spacer offers enhanced airflow management and engine efficiency, making it an excellent choice for enthusiasts seeking to optimize their BMW's performance. Whether you're looking to improve throttle response or increase power output, the aFe Silver Bullet Spacer provides a simple yet effective solution to elevate your driving experience.
