Porsche Performance Intake Plenum - IPD 87174

All Performance Plenums include a new throttle body gasket.

The revolutionary and patented design of the IPD Porsche Plenums improve intake air flow by replacing the factory plastic "T" style design with a more efficient, cast aluminum "Y" design. This innovative “Y” diversion area of the IPD Plenums split and channel intake air flow reducing air flow turbulence and increasing air flow velocity. This superior and proven design ultimately results in considerable power gains throughout both horsepower and torque curves. Performance is also enhanced with our uniquely dimpled interior surfaces which create improved boundary layers further optimizing intake air flow characteristics.

The 87174 Plenum utilizes the factory 74mm throttle body. This version provides impressive power gains throughout the entire power band, especially in the midrange where it's most critical and most enjoyed.

This application is recommended for enthusiasts looking for considerable performance gains without pushing the performance envelope. Max horsepower gain is 14 HP and max torque gain is 12 lb/ft which all come in around 5600 RPM. Power gains are realized throughout the entire power band without any loss in power.

The IPD Plenum will provide the most impressive power gains of any engine upgrade available and will truly transform your Boxster/Cayman driving experience. The IPD Plenum is the best modification on the market and will further compliment other mods such as exhaust, software and beyond.
