Best TMIC on the market! Extreme Turbo Systems has designed a direct bolt on top mount intercooler for the 08-21 Subaru STI. This intercooler features a large 21x7x4 core with 33 charge rows! Most competitor intercoolers have between 24-25 charge rows. By having 33 charge rows our intercooler has 62 heat transfers vs our competitors 48 heat transfer place which results in a greater heat transfer area. This core is designed specifically for 2008+ Subaru STI this is not an off the shelf core. Unlike our competitor's intercooler, we require no modifications to the a/c line that runs behind the intercooler. The intercooler also uses studs to mount the blow off valve instead of bolts, this means no stripping out the holes when over tightened. This intercooler has been designed for maximum performance.
