In testing the 991 GT3/RS/R we found the intake to be a rather restrictive weak point of the car. By increasing the throttle body to 93mm and replacing the center plenum with the Dundon revised unit, you can allow the car to breath better and make more power. In combination with the Dual Reverse Cone Airbox, the pressure losses net 0.1psi versus the OE duo at 0.6psi.
- Compatible with 991.1 GT3/RS/R and 991.2 GT3/RS/Touring)
- Kit includes "Big Mouth" center plenum, 93mm throttle body, and adapter harness
- Atmospheric pressure losses reduced to 0.1psi (from 0.6psi factory)
