IPD Intake Plenum for Porsche 997.1 Turbo 2006-2009

The 997.1 Turbo's Mezger-based 3.6L responds strongly to better airflow after the intercoolers, and IPD offers two plenums for it. The 74mm version bolts to the factory 74mm throttle body for stock or lightly modified cars, while the 82mm Competition version is machined for a genuine Porsche GT3 82mm throttle body for cars with bigger turbos, intercoolers and more aggressive software. IPD's Vision Motorsports test showed a stock 997 Turbo gaining 47 wheel horsepower and 35 lb-ft with the plenum.
