The aFe Silver Bullet throttle body spacer installs between the throttle body and intake manifold on the Ford Ranger, Explorer, and Mazda B4000 with the 4.0L OHV V6 (excludes SOHC). The serrated helix bore adds turbulence to the incoming air for crisper throttle response, more low-end torque, and better fuel economy, without the whistle of helix-only spacers. Machined from T-6061 billet aluminum.
