Overview

IPD's 82mm Competition plenum for the 981 Cayman comes in three engine-specific versions: the 2.7L Cayman, the 3.4L Cayman S and GTS, and the 3.8L GT4. Each one replaces the factory plenum with IPD's cast aluminum Y design and is machined for a genuine Porsche GT3 82mm throttle body. On a GT4 tested by SP Engineering, the plenum and 82mm throttle body added 18 wheel horsepower and 17 lb-ft.

Features

  • Three engine-specific castings: 2.7L, 3.4L and 3.8L GT4
  • GT4 dyno: 18 WHP and 17 lb-ft with plenum and 82mm throttle body
  • 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
