Intake Manifold Plenum

Intake Manifold Plenums for Porsche 911

The plenum is the chamber that collects air after the throttle and feeds it to each cylinder. On a tuned turbocharged engine, the factory plenum can become a restriction and distribute air unevenly. A larger, better shaped plenum improves flow and helps a modified engine make power more consistently across the rev range.

Our plenum collection is focused on do88 parts for the Porsche 911. We carry the do88 Performance Intake Plenum for the 997.2 Turbo, the do88 Intake Plenum for the 991 Turbo and 991.2 Carrera, and the do88 Cast Aluminum Intake Plenum for the 992. Each is a direct replacement for the factory part, built to support higher boost on tuned cars while keeping a clean, factory style fit under the engine lid.

OneFastShop is an authorized do88 dealer, and every plenum is genuine with full manufacturer warranty. Have questions about which plenum suits your 911 and tune? Get in touch with our team.
