Dundon Motorsports 2014-2016 Porsche 911 GT3/R OEM GT3 Touring Airbox, 93mm Throttle Body, Dundon Center Plenum

Help your 991.1 GT3 BREATHE!!!

Dundon Motorsports found in their exhaust development and testing of the 991.2 GT3 and RS that they are intake limited both through the factory airfilter box and through the 82mm Throttle body. A bit of history. The Bosch 82mm Throttle body is the largest Bosch makes and was used as far back as the 996 GT3 which made 380hp. The Air filter box used on the 991.2 GT3 and the 991.2 GT3RS originally showed up on the 2013 991 Carrera S which makes 350hp. Your 991.2 GT3 is rated at 500hp, so you can see just from these numbers that the intake side of things is a constriction.

In their testing they found the the stock airbox to be about a 0.2-0.3psi pressure loss and the 82mm throttle body to be about 0.3-0.4psi of pressure loss. Naturally aspirated engines make power from the force of the atmosphere pushing air into the engine, so every 0.1 psi helps! Our combo of 93mm Throttle Body and Dual Cone Airbox reduces the losses to under 0.1psi.

They tried both our airbox and the 991.2 GT3 Touring Airbox and found our airbox to only be slightly better but the Touring box is less expensive, so we decided to include the Touring airbox for the single opening decklid cars. (991.1 GT3, 911R and Touring)
