How to Install an Aftermarket Intercooler in Your MK7

Loading...

 

The intercooler in a turbocharged vehicle is responsible for lowering the temperature of the air passing through the turbocharger before it gets to the engine. When a turbine spins, it compresses air molecules which then become hot, so an intercooler cools those molecules before they reach the combustion chamber. Colder air is more dense, which allows more air and fuel to combust in the engine and generate more power.

 

Why should I upgrade my intercooler? 

Your MK7’s stock intercooler can adequately manage the compressed air passing through your engine, but every intercooler’s worst enemy is heat soak. Heat soak occurs when there is too much heat for the intercooler to manage, causing more warm air molecules to reach the combustion chamber, decreasing performance. This can occur during heated track sessions or simply by overworking your car on a particularly hot day.

An upgraded intercooler is designed to catch more cold air and can tolerate much more heat than a factory intercooler can. It doesn’t provide any performance benefits on its own, but can minimize the effects of extreme heat that would otherwise result in a performance loss. Investing in a higher-quality aftermarket intercooler is a good idea if you frequently drive and/or track your MK7 in a hot climate.
