Porsche introduced the 987.1 Boxster s with the 3.2 liter engine from the 986 Boxster s. This plenum version provides impressive power gains throughout the entire power band, especially in the midrange where we enjoy it most. The 74mm Boxster s ipd plenum and upgraded 74mm (from 68mm) throttle body (must purchase seperately) is recommended for Boxster s enthusiasts looking for considerable performance gains. Performance gains can be felt throughout the entire power band making the Boxster driving experience even more visceral.

The ipd Boxster s plenum will provides the most impressive power gains of any engine upgrade available and will truly transform your Boxster driving experience. The 74mm ipd plenum is the best Boxster s modification on the market and will further compliment other mods such as exhaust, software and beyond.
