In testing the 991.2 GT3 and RS we found the intake to be restrictive.  With the addition of the larger 93mm Throttle Body and Center Plenum you can allow the car to breath better.  We measure this by comparing the atmospheric pressure outside of the Plenum to the pressure inside the plenum.  Ideally we want no differences.  This change helps reduce pressure losses from about 0.6psi down to 0.1psi when used with our Dual Reverse Cone Airbox.  




This Kit fits 991.1 and 991.2 Winged GT cars (991.1 GT3/RS, 991.2 GT3/RS), The Touring has a slightly different part
