The Best Bolt on Performance Upgrades for Late Model Porsches

IPD logo

The perfectly balanced mid engine platform of the 987 combined with a drop top convertible make for a truly liberating Porsche diving experience. The 987's were delivered slightly under powered from the factory so as not to rain on the Carrera's parade. The IPD Boxster intake plenum delivers increased performance that puts the Boxster in the ring with the famed Carrera.

The IPD Plenum out performs every other intake system on the market. Don't be fooled by other competitors claiming to offer Plenums. All factory Porsche air distributors are of the "T" variety and therefore suffer from less than ideal air flow and reduced intake air speed.

The Boxster IPD Intake Plenums are available in 3 versions, each one specifically designed to meet the performance requirements of varying Boxster enthusiasts. From mild to wild, it all depends on how fast you want the wind in your hair.

The genius and power behind the IPD plenums comes from the patented "Y" style design and optimized diversion areas to deliver real and impressive power that will transform your Boxster performance and heighten your Porsche driving experience.
