One of the most overlooked upgrades on a 996TT® is the Intercooler. Many owners upgrade turbos and run 1.2+ bar of boost producing twice the heat without addressing this issue. The primary goal of a upgraded intercooler is the lower the intake temperature, prevent detonation, and keep the car from pulling timing. Cooler intake temperatures equals horse power period. Over the years we have manufactured and tested various intercoolers on our own project cars. We have both direct replacement 3″5 sport Intercoolers as well as 4″5 race Intercoolers for higher HP applications. We also offer custom made monster 6″ intercoolers for special requests. We use only high quality Bell cores and produce the entire intercooler in house.
