aFe Power Silver Bullet Throttle Body Spacer for Select Ford & Lincoln 2004-2010 (V8-5.4L) 46-33002

Fits select 2004-2010 Ford F-150, F-250/F-350 Super Duty, Expedition, and Lincoln Mark LT (V8-5.4L).

The aFe Power Silver Bullet throttle body spacer is engineered to improve off-idle torque and throttle response by optimizing the air-fuel charge entering the engine. Precision-machined from T-6061 billet aluminum, this spacer features a unique serrated and helix-shaped entry design. This combination creates high-velocity turbulence within the intake manifold, leading to better air-fuel atomization and more complete combustion. Unlike standard helix spacers, the Silver Bullet design is specifically tuned to eliminate the annoying whistling sound often associated with throttle body spacers.
