Intercooler Kit + Downpipe – Audi A3 8L / Golf 4 GTI

Description

This complete upgrade kit combines a high-flow intercooler with a 3-inch downpipe for 1.8T VAG Group models. This combination results in lower intake temperatures, improved turbo efficiency, and freer exhaust flow, resulting in noticeably higher performance in both standard and tuned 1.8 Turbo engines.

The intercooler increases cooling capacity thanks to a 500x155x70mm core and large 68mm connections. The downpipe is a 76mm (3”) two-piece design with a connection for the standard K03 turbo and equipped with a lambda connection. A perfect kit for anyone looking to upgrade the 1.8T engine series with more flow, greater stability, and faster turbo spooling.

Suitable for vehicles from model year 1997–2006 with 150–180 hp 1.8T engines.
