Overview

The 991.2 GT2 RS uses the same 74mm IPD plenum as the 991.2 Turbo, a cast aluminum Y merge that replaces the factory air distributor. Because the GT2 RS charge plumbing is unique, IPD makes GT2 RS-specific Y-pipes, available here as an optional add-on so the whole intake path can be upgraded together.

Features

Shares the 991.2 Turbo 74mm plenum casting
GT2 RS-specific Y-pipe add-on, in cast aluminum (carbon currently unavailable)
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
Quicker boost response and a more linear power curve on stock and modified cars
O-ring sealed throttle body flange with the vacuum and vent fittings in place

What's Included

IPD cast aluminum plenum with installed vacuum and vent fittings
IPD high flow Y-pipe when the Y-pipe add-on is selected
