The Porsche Cayman S was created with a lot of potential air flow. The engine itself is very aspirated. Having a lot of air is a great thing when it comes to power; however, if that air isn’t being use effectively, then you’re losing power. Agency Power recognized this flaw and decided to make the Cayman S more efficient by opening up the gateway for the air to flow through. This throttle body is spec’d from road and dyno testing to give the best responsive for the 987 Cayman Boxster engine. Since the engine works off of pulses, it is not as important of the shape of the T-Pipe but the throttlebody diameter and how much useable air flow you are getting.
The Agency Power Performance Plenum Kit for the Porsche Cayman S is the perfect tool to get your Cayman to it’s full potential. They have done their homework and dyno tested it to ensure you’re getting the best performance you can. Agency Power’s Racing Plenum uses a combination of factory Porsche parts and our custom made aluminum T-Pipe to guarantee you an OEM look, fit, and finish with no troubles or false claims. As tested on both left and right hand drive vehicles, the plenum does not impede shifter cables or other sensors functionality. The plenum is a direct plug and play and includes the necessary adapters, clamps, silicone hoses to fit to your car. Tuning is not required, though as tested with our VR Tuned, gains 25 wheel horsepower which is approximately 35bhp.
