987 1 Plenum 01 211 800 600 80 sm

The innovative and patented design of the IPD Porsche Plenums improve and optimize intake air flow by replacing the factory plastic “T” style air distributor with our more efficient, cast aluminum “Y” designed Plenum. This superior merge collector splits and channels intake air flow, reducing air turbulence and increasing air velocity. This proven design delivers impressive net power and torque gains across both power bands from launch to redline.

997 Turbo Y Pipe AWe also offer Y-Pipes for turbo applications which feature an accentuated merge collector area that manages the intake air flows from each intercooler so they meet in a more parallel manner as air enters the throttle body, minimizing turbulence and increasing boost response. The combination of the Plenum and the turbo Y-Pipe are guaranteed to deliver substantial power and torque gains sure to elevate your Porsche driving experience to the next level.

IPD Plenums have earned the reputation of being the single best “bolt on” performance upgrade you can install on a late model (1999-Current) Porsche. These products provide the best power per dollar return in the Porsche after-market industry today. They have been tested, challenged and proven repeatedly to deliver our impressive, claimed power gains.
