Already installed the Mishimoto charge pipe kit on your WRX? Complete the build by adding this top-mount intercooler. Featuring a 4" thick core of 625in3 volume, it's one of the biggest on the market. TIG-welded cast aluminum end tanks and a dense bar-and-plate core provide ideal thermal transfer. Our testing showed a 35°F temp drop & a +15whp/ +8wtq power increase on a WRX w/ our downpipe & stage 2 tune. Installation is a breeze; no modifications needed & can be done in under an hour. We also include a silicone coupler, air splitter, & intercooler-to-TB hose. Available in Stealth Black & Sleek Silver, backed by the Mishimoto Lifetime Warranty.
