The aFe POWER 46-32007 Silver Bullet Throttle Body Spacer is a precision-machined performance upgrade for the 2011-2012 Dodge Challenger SRT8 6.4L V8 HEMI. This 0.75-inch thick billet aluminum spacer installs between the throttle body and intake manifold, creating controlled turbulence via its serrated helix design to improve fuel atomization, throttle response, and overall power delivery while eliminating common whistling noises. The raw aluminum finish adds a clean, aggressive look to the engine bay, and the kit includes high-quality gaskets for a direct bolt-on installation with no modifications or tune required.
