Featuring a sleek and stylish design that complements your vehicle's aesthetics perfectly, this top-of-the-line intercooler boasts numerous impressive features, including its CNC'd billet aluminum construction, advanced cooling capabilities, and improved airflow properties. Designed to fit within the constraints of the tightly packed engine bay, this intercooler is the perfect choice for those looking to upgrade their Subaru WRX's functional capabilities or simply looking for an added touch of style.
Quality Construction
Manufactured with a 19in x 7in x 4in cross-flow bar and plate construction core, the GrimmSpeed Billet Top Mount Intercooler offers a 63% increase in total volume and 209% more flow area than the stock top mount models. The in-house pressure testing process ensures that the product is clean, sealed, and guaranteed to work as required, with no leaks or failures over time.
The highlight of this product is the innovative design of billet aluminum end tanks that ensure equal flow distribution and minimum pressure drop. The use of 4-axis CNC milling has resulted in precise and consistently crafted end tanks, making the manufacturing of the intercooler a breeze. The intercooler also features a leak-resistant throttle body connection with a pre-installed double O-Ring, and a replacement chargepipe coupler is included with it.
