Darkside Audi S3 Intercooler with Alloy End Tanks for Mk5 / MK6 Platform

This intercooler is an upgraded version of the original Audi S3 8P Intercooler. It is a popular upgrade for a wide range of VAG Vehicles as it is a direct fit (with the longer bolts supplied) and has been used in applications well over 400bhp
