GrimmSpeed - Subaru 15-21 STI - Front Mount Intercooler Kit (Raw Core / Red Pipe)
Meticulous Engineering, Unparalleled Craftsmanship
GrimmSpeed Intercoolers have set the gold standard of how a high-performance heat exchanger should be crafted. Our intercoolers have always maintained the delicate balance of low-pressure drop and high-temperature rejection, which is vital to safety and performance for your turbocharged Subaru engine. How can we possibly improve upon what is already touted as the best? The answer is exactly what enthusiasts have been anticipating for years: Introducing the GrimmSpeed 2015+ WRX and STI Front Mount Intercooler Kits!

The core is the most important aspect of the intercooler. It’s difficult to design the most efficient core possible; get it right and you have phenomenal results, get it wrong and you end up with an expensive paperweight. We were able to channel over a decade of intercooler production knowledge into creating a totally custom design from the ground up with our tested internal and external specifications to maximize the performance and deliver the best cooling option on the market. The beautiful cast aluminum end tanks were carefully designed alongside the core for the most efficient and optimal flow characteristics for all driving situations. The result of our hard work is an intercooler designed, welded, and tested right here in Minneapolis, MN by a team of skilled engineers and welders with extremely minimal pressure drop and extraordinary heat rejection.
Along with amazing performance, perfect vehicle fitment and mounting are essential. We designed robust steel mounting brackets that will keep the unit from shifting around even during hard track driving. We learned from other manufacturer’s shortcomings and improved upon them. Unlike other kits, our front mount intercoolers retain a HUGE core, but do not require cutting portions of your bumper cover or light housings, and don’t require replacing or relocating components such as the washer tank or coolant reservoir in order for the piping to fit.
An impressive core like the one we’ve designed means nothing without a complimentary, properly engineered piping kit. GrimmSpeed kits are comprised of thick aluminum tubing, precisely machine-bent with large radius bends for maximum flow and perfect fitment every time. The pipes are bead rolled at each end to lock together with the included 5-ply silicone couplers so you don’t have to worry about blow-offs under high boost. They are then covered in gorgeous, durable red or black wrinkle powder-coat finish that looks incredible and matches your other GrimmSpeed parts!
