HKS 08+ STi FMIC *Requires Smaller Battery 71007-AK001 & 70020-BF010*

HKS is well-known for making performance parts for Japanese sports cars, and their front mount intercooler for the 2008+ Subaru STi is a prime example of their focus on improving engine performance. This intercooler is designed to replace the factory top-mount unit, offering a significant upgrade in cooling efficiency for your turbocharged engine. By placing the intercooler in the front of the vehicle, it can take advantage of cooler ambient air, which helps to reduce the temperature of the air charge entering the engine. Cooler intake air means a denser air charge, allowing your engine to make more power and respond more crisply.

This intercooler kit is a substantial upgrade, featuring a large core designed for maximum heat dissipation. The construction uses durable materials to withstand the rigors of performance driving. Installing a front mount intercooler like this often involves modifying or relocating other components to make space. For this specific HKS kit, you will need to use a smaller battery (part numbers 71007-AK001 and 70020-BF010 are recommended by HKS) to ensure proper fitment. This is a common consideration when upgrading to a larger front-mount setup, as it frees up the necessary space in front of the radiator.

Upgrading your intercooler is a key step for anyone looking to push their STi's performance further, especially if you've already modified other parts of the induction or exhaust system. This HKS unit is a well-built option that aims to provide improved cooling performance, which can be crucial for maintaining consistent power output, particularly during extended driving sessions or track use. Please note that this part is not CARB approved and cannot be shipped to California.
