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, cats 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.
Innovative Pro Design (IPD) was founded in 2004 by Mike Turbo Kirakosyan. The IPD Plenums were conceived, developed, tested, proven and manufactured in the heart of the Porsche Tuning capital, Southern California. The entire IPD team is dedicated to providing the absolute best after market performance products for Porsche. IPD stands behind each and every plenum and their promised power claims with a 100% money back guarantee if not completely satisfied after 30 days.
