Get faster, smoother throttle response where you need it most.

Installed in your throttle body’s Venturi tube, the precision-engineered sleeve reduces the diameter and accelerates the velocity of your air-fuel mix. Add the thinner butterfly valve and less obstructive shaft, and you’ve got faster, more even throttle response through low- and mid-range.

For better top-end throttle response (90-100% open throttle position), use the kit’s larger butterfly valve without the sleeve.

Either way, you can:

• Get faster, smoother throttle response

• Eliminate high-end flow loss by lowering flow restriction

• Install/remove without damaging the OEM throttle body

• Count on maintenance-free reliability after installation
