aFe Silver Bullet Throttle Body Spacers for BMW 5 Series (E60) 2006–2010 V8-4.8L

Designed to sit between the throttle body and intake manifold, this Silver Bullet spacer from aFe uses a serrated/helix entry to induce controlled turbulence just before the air enters the engine, improving throttle response while helping increase horsepower and torque and promoting better fuel efficiency. Machined from durable T-6061 billet aluminum, the spacer also addresses the whistle commonly found with helix-only designs, delivering a refined, high-flow upgrade for BMW V8 4.8L applications.
