Product Description

The aFe Power 46-33020 Silver Bullet Throttle Body Spacer is a performance engine accessory engineered to improve airflow into the intake manifold on select Ford applications. Made from precision CNC-machined 6061-T6 billet aluminum, this spacer features a proprietary serrated/helix internal profile that creates controlled air turbulence just before the throttle body. This optimized airflow can help increase horsepower, torque, and throttle response without extensive engine modifications.

Designed as a direct-fit throttle body spacer, the 46-33020 installs easily using existing factory mounting locations and includes all necessary gaskets and hardware. It's ideal for enthusiasts looking for a straightforward upgrade that enhances responsiveness and performance, particularly on Ford Mustang GT V8 5.0L engines from 2011-2023. Some implementations also list fitment with Ford Super Duty trucks with 7.3L V8 engines when used with factory intake systems - verify your specific intake compatibility before purchase. CARB compliance varies by region, so check local regulations prior to installation.
