The aFe Silver Bullet throttle body spacer mounts between the throttle body and intake manifold, where its serrated/helix design creates air turbulence that improves throttle response and builds low-end torque and horsepower. Machined from T-6061 billet aluminum, the serrated entry also eliminates the whistle common to helix-only spacers. It bolts to the factory mounting locations and fits Acura TLX/MDX/RLX/RDX and Honda Pilot/Ridgeline/Odyssey/Passport models with the 3.5L V6.
