Porsche 911 997/GT2/RS Turbo Coolant Elbow Pipes for Oil Exchanger

This is our newly revised March 2026 Version with Internal Welding For Reinforcement!

Circuit Werks offers a solution for the weak factory plastic units that are prone to failures.

This set of stainless steel coolant pipes replaces the plastic elbow's that attach to the engine block for a permanent solution.

This product fixes a lesser known issue involving the plastic coolant elbow pipes that run to the two oil coolers(heat exchangers). These pipes are molded plastic and have a very thin wall where the pipe connects to the engine with an O-ring seal. The problem is that over time and mileage, the thin plastic wall will break down at the O-ring slot (its weakest and thinnest point) causing coolant to leak. 

This item is considered preventative maintenance and should be installed on all 997 Turbo (2007-2009), 997 GT2 (2008) and 997 GT2RS models. This part is not required or compatible with 996 Turbo models (which already have a metal tube).
