Radiator

The Subaru WRX has a rally pedigree unlike any other mass-market vehicle. When you step into your 2022+ WRX, you're stepping into 30 years of hard-earned lessons in building a performance car that's at home on any surface. But going from racing to commuting comes with some sacrifices, especially in the cooling department. While Subaru's rally cars get top-of-the-line cooling systems built for going all-out through miles of forest, gravel, and tarmac, the WRX gets the accountants' choice of plastic end tanks and loosely packed core. With this Mishimoto performance aluminum radiator, you can take your WRX closer to its rally roots and push it to its limits.----Our radiator features aluminum end tanks that are precision TIG-welded to withstand the vibrations and impacts that rally, track, or everyday driving throw at it. To help keep your FA24 boxer engine cool for miles of wide-open-throttle, we've sandwiched a two-row, 36 mm-thick core between those end tanks. This core features densely packed and louvered fins that effectively circulate air throughout the core for maximum heat transfer. The larger core also translates to a 32% increase in core volume, meaning our radiator can pull more heat out of more coolant, for more efficient cooling. A slotted drain plug helps direct coolant into your drain pan, instead of onto the floor during service. Like all Mishimoto radiators, this 2022+ Subaru WRX performance aluminum radiator is backed by our Mishimoto Lifetime Warranty.
