The aFe Silver Bullet throttle body spacer creates turbulence in the air flow just before it enters the engine, increasing horsepower and torque while improving throttle response and fuel efficiency. Machined from durable 6061-T6 billet aluminum, its serrated/helix entry design generates that turbulence while significantly reducing the whistle associated with standard helix spacers. It fits the 2.0L Scion FR-S, Subaru BRZ, and Toyota 86 twins.
