997.1 GT2 IPD Intake Plenum

Turbo customers looking to increase engine power without pushing the motorsport envelope to redline would best benefit from the 74mm IPD Turbo Plenum. This version of the 997 Turbo plenum utilizes the factory 74mm throttle body and delivers impressive performance gains for both stock and slightly modified Turbos with exhaust and software. Beyond these performance mods we recommend upgrading to the larger 82mm IPD Turbo Plenum. The 74mm IPD Turbo Plenum is also designed to perform with the higher flowing IPD “Y” Pipe.
