IPD 2013-2016 Porsche Cayman, S, GTS, Spyder, GT4 (981) “Competition” Plenum Kit

Fits:

2013-2016 Porsche Cayman 3.4L Models (S, GTS, Spyder, GT4)

3.4L Engines for “S” models and 2.9L Engines for “non-S” models.

Description:

We only offer “Competition” versions of the 981 Plenums which upgrades the factory 74mm throttle body with the larger 997 GT3 82mm throttle body. This combination has proven to be considerably more popular and deliver even more performance. This Competition version will work with both 3.4L “S” and 2.9L “Non-S” applications.

The 981 intake is nearly identical to the 987.2 intake. Porsche made a few upgrades with the 981, most notably being that the 981 draws outside air from both driver and passenger air intakes instead of the driver’s side only as previously found with all 986, 987 and 987.2 applications. IPD has developed a custom silicone hose designed to perfectly fit the larger 82mm TB and considerably improve air flow.

The new 981 Plenums also benefits from the internal dimpling effect that we are now implementing on all future Plenums. This internal dimpling allows us to control the boundary layer and maximize air flow. Just like a dimpled golf ball travels farther than a smooth golf ball. Controlled turbulent air creates less friction and “tumbles” over a given area more efficiently.

Power gains with the 981 Competition Plenum are virtually the same as with the 987.2 Competition Plenum, putting down 20 horsepower and 16 foot pounds of torque at the wheels. The bulk of the power gains from the IPD Plenum begin around 4000 rpm, continues all the way through to redline and become fully realized in the 6000 rpm range. IPD performance gains stay above both factory power curves throughout the entire rev range

Includes:

Genuine 997 GT3 82mm Porsche Throttle Body

This is the larger Genuine Porsche Throttle Body from Germany required to fit the larger 82mm TB

IPD Porsche Plenums and Y-Pipes

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. IPD also offers Y-Pipes for turbo applications. Our turbo Y-Pipes feature an accentuated merge collector area that allows the intake air flows from each intercooler to meet in a more parallel fashion as air enters the throttle body, minimizing turbulence and increasing boost response. The combination of the Plenum and the turbo Y-Pipe will deliver substantial power and torque gains guaranteed to transform your Porsche driving experience. IPD Plenums have earned the reputation of being the single best “bolt on” performance upgrade you can possibly install on a late model Porsche. The IPD Plenums 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. Every IPD Plenum and Y-Pipe in our product line goes through a very rigorous and scientific R & D program backed with extensive dyno testing and tuning to deliver the maximum engine output possible.
