aFe POWER 46-33002 Silver Bullet Throttle Body Spacer; Ford F150 04-10 V8-5.4L
Silver Bullet throttle body spacers are constructed out of durable 6061-T6 billet aluminum and utilize a serrated/helix design that creates turbulence in air flow at the point just prior entry into the engine. This turbulence helps the air/fuel charge burn completely for increased horsepower, torque and throttle response. This throttle body spacer only works with aFe Stage-2 intakes part number 51-10512, 54-10512, 51-80512 and 54-80512.
