IPD 74mm Intake Plenum for Porsche 991.2 Turbo / Turbo S 2017-2019

The 991.2 Turbo and Turbo S already make serious power, but the factory air distributor between the intercoolers and throttle body is a T-shaped plastic part that forces two charge streams to collide head-on. IPD's cast aluminum 74mm plenum replaces it with a patented Y-shaped merge, so boosted air from both banks meets at a shallow angle and keeps its speed into the throttle body. On IPD's own Cobb SoCal dyno sessions a stock 991.2 Turbo S picked up more than 45 wheel horsepower in the midrange from the plenum alone.

Features

• IPD dyno, stock 991.2 Turbo S: 45+ WHP and 55+ lb-ft at 4,300 RPM with the plenum; 55+ WHP and 70+ lb-ft with plenum and Y-pipe
• IPD's patented Y-shaped merge in place of the factory T-style air distributor
• Cast aluminum construction, made in the USA by IPD in Huntington Beach, California
• Dimpled internal surface designed to keep air moving smoothly through the merge
• Quicker boost response and a more linear power curve on stock and modified cars
• O-ring sealed throttle body flange with the vacuum and vent fittings in place
