All of the ipd competition plenums utilize the next largest size throttle body offered by Porsche. In this case, the competition Carrera upgrades the factory oe 74mm throttle body with Porsches 82mm 997 GT3 throttle body. All of our competition plenums are designed to perform with cars equipped with high performance exhaust systems. The more extensive the exhaust system (headers, kats and mufflers) the better. Optimizing air intake and exhaust together creates a balanced performance package that allows the engine to inhale and exhale more air thus creating more power and torque.

Gains vary depending on pre-existing mods and quality of after-market exhaust installed. As we all should know, horsepower and torque become harder to find and typically more expensive as we climb the proverbial performance ladder. That being said, performance components yield different power gains depending on the order they were installed. Ipd tests and evaluates all products on bone stock cars, this establishes a level playing field and a better apples to apples comparison. The competition Carrera plenum however is designed to work with applications that are already moderately to heavily modified. Power gains will vary with each Carrera, but the bottom line is, there will be noticeable and impressive gains that are sure to make any Porsche Carrera driving enthusiast smile. Power improvements will be fully realized once the factory ecu/dme makes all the necessary adaptation requirements. This process can be expedited with a series of hard pulls or spirited full throttle acceleration runs through the gears. Of course this should only be performed on a closed course circuit.
