Overview

The 987.1 Cayman and Cayman S use a factory plenum that IPD replaces with a cast aluminum Y design. Pick the 74mm plenum for the 2.7L or 3.4L, which keeps your factory 74mm throttle body, or the 82mm Competition plenum for 2007-2008 cars stepping up to a genuine Porsche GT3 82mm throttle body. IPD positions it as a base for exhaust and software upgrades.
