They have designed a direct bolt on top mount intercooler for the 08+ Subaru STI.  This intercooler features a large 21x7x4 core with 39 charge rows!  Most competitor intercoolers have between 24-25 charge rows.  By having 39 charge rows their intercooler has 78 heat transfers vs the competitors 48 heat transfer place which results in a greater heat transfer area.  This core is designed specifically for the 2008+ Subaru STI this is not an off the shelf core.  The end tanks are hand built and hand ported for maximum flow, fit and finish.  Unlike other competitors intercooler this one requires no modifications to the a/c line that run 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.
