The aFe Silver Bullet throttle body spacer is a billet T-6061 aluminum spacer with a serrated/helix entry that creates controlled turbulence just before the intake manifold to boost throttle response, torque and horsepower while reducing the whistle found in other helix-only spacers. Precision machined construction increases air volume for better performance and it carries a two-year limited warranty; fitment includes BMW 335i/435i family applications noted in the product data.
