Product Description

The aFe Silver Bullet Throttle Body Spacer (46-30002) is a precision bolt-on performance upgrade for the 2014-2018 Mazda 3 equipped with either the 2.0L or 2.5L four-cylinder engine. CNC-machined from lightweight 6061-T6 billet aluminum and finished in a black anodize, it installs between the throttle body and intake manifold using all factory mounting locations - no modifications or drilling required. By lengthening the intake tract and introducing the patented Serrated/Helix entry design, the spacer increases intake air velocity and creates controlled turbulence at the manifold inlet that promotes a more thorough air/fuel mix and more complete combustion.

The result is dyno-proven gains of up to +3 HP and +3 lb-ft torque along with improved throttle response straight out of the box. The serrated edge of the helix design specifically addresses the intake whistle common to helix-only spacers. A gasket is included for a leak-free seal, and the spacer is compatible with aFe POWER cold air intake systems 56-10009R and 56-10009D for owners looking to combine intake and throttle body upgrades.
