Are you ready to start turning your 2015-2021 GT Mustang into a performance-driven machine? If so, than this premium-quality aFe Silver Bullet Throttle Body Spacer (46-33020) is a definitely must-have! Be sure to order yours from CJ Pony Parts now!

aFe designed their premium Silver Bullet throttle body spacers to create turbulence in the air flow just prior to entry into the engine, which will increase horsepower, torque and improve throttle response and fuel efficiency in your newer Mustang. Your all-new Silver Bullet throttle body spacer is constructed from durable 6061-T6 billet aluminum and will use a unique serrated/helix entry to create turbulence at the manifold while eliminating the annoying whistle found in other helix-only throttle spacers. You'll absolutely love the immediate increase in power and performance this throttle body spacer provides your GT pony, but you can take things a step further by upgrading the cold air kit and air filter as well.
