The aFe Silver Bullet throttle body spacer mounts between the throttle body and intake manifold, using a serrated/helix entry to create air turbulence that improves throttle response and adds low-end torque and horsepower. It is precision-machined from T-6061 billet aluminum, and the serrated design eliminates the whistle found on helix-only spacers. The spacer bolts to factory mounting locations and fits the Toyota Tundra, Sequoia, 4Runner and Land Cruiser plus Lexus GX470/LX470 with the 4.7L V8.
