The aFe Silver Bullet Throttle Body Spacer (Part Number: afE46-37001) is engineered to enhance engine performance by creating turbulence in the airflow just before entry into the engine. This turbulence increases horsepower and torque while improving throttle response and fuel efficiency, making it an ideal upgrade for enthusiasts seeking better engine responsiveness. Crafted from durable T-6061 billet aluminum, this spacer features a unique serrated and helix entry design that optimizes airflow dynamics and reduces unwanted whistle noise common in other helix-only spacers.
The Silver Bullet Spacer is specifically designed to fit a range of Honda and Acura models, including Honda Civic Si from 2012 to 2015, Honda Accord from 2008 to 2009, and Acura TSX from 2009 to 2012. Its precise engineering ensures ease of installation and seamless integration with your vehicle*s existing intake system. The spacer's robust construction guarantees long-lasting performance under demanding driving conditions.
By increasing airflow efficiency, the aFe Silver Bullet Spacer helps maximize engine output without the need for extensive modifications. Its compliance with EPA standards and certification under carb EO number D-550-47 ensures that it meets regulatory requirements for emissions and performance. The lightweight design adds minimal weight impact while delivering noticeable improvements in engine responsiveness, making this spacer a reliable upgrade for performance-minded drivers.
