Overview

The 987.1 Boxster changed engines mid-generation, so IPD makes four plenums for it: one for 2005-2006 2.7L and 3.2L cars, separate 2.7L and 3.4L versions for 2007-2008 that keep the factory 74mm throttle body, and an 82mm Competition plenum for 2007-2008 cars upgrading to a GT3 82mm throttle body.

Features

  • Separate castings for 2005-2006 and 2007-2008 engines
  • 82mm Competition plenum for 2007-2008 cars
  • IPD's patented Y-shaped merge in place of the factory T-style air distributor
  • Cast aluminum construction, made in the USA by IPD in Huntington Beach, California
  • Dimpled internal surface designed to keep air moving smoothly through the merge
  • Replaces the factory mid-engine plenum with a direct-fit IPD part
  • Works with exhaust and software upgrades

  • IPD cast aluminum plenum
  • Genuine Porsche throttle body when the throttle body add-on is selected
