D3 Street Header/93mm Intake Kit/Optional Lifetime Muffler Power Package (2018-2019 991.2 GT3)

This is the most complete, well-rounded power package around for the 991.2 GT3 4.0L. With careful consideration and many design, engineering and tuning hours, we have extracted impressive power, torque and drive-ability out of the 991.2 GT3 4.0L engine. The best part: no compromises. 

PDK sees a max improvement of 47 lbft of torque and 38 whp

Manual sees a max improvement of 53 lbft of torque and 31 whp

PEAK output OVER 473 horsepower at the wheels!!!

By reducing the pressure losses in the intake and allowing a more "free flow" into the engine the engine makes power two ways: First, less engine power is used to overcome the parasitic losses of the stock intake tract. Second, we're able to get more high pressure air to the intake valve (to cram in more air into the cylinder). Both of these translate into more power. On a car that uses "Ram-Air" to it's advantage (scoops on the decklid), the gains are more than can be measured on a static dyno. Finally, we utilize Cobb's Accessport to free up the remaining power that the ECU has been holding back. The result? The car drives like an absolute rocket!!  Kit Includes:

• Dundon Dual Reverse Cone Airbox
