TurboXS Gigantic Top Mount Intercooler 02-07 WRX/STI
Your stock intercooler is pretty small. You see that bracket that's sitting empty to the side of it? That's for the larger intercooler that the STi car gets. There's obviously a lot more room under that hood. What are you waiting for?
The TurboXS Gigantic Top Mount Interooler is -- bar none -- the largest top-mount intercooler ever stuffed under the hood of a WRX. Compare the specs:
Stock intercooler: 297 cubic inches
TurboXS Gigantic Top Mount Intercooler: 634 cubic inches
Yep, that's more than TWICE the core volume, for twice the cooling capacity, plus a lower pressure drop than the stock intercooler. This intercooler is 18% bigger than the next-largest one on the market!
Massive CNC-machined aluminum intakes use the stock dual-inlet routing for efficient spread of air across the core. CNC forming, vs. casting, reduces the end tank weight by a whopping four pounds, and provides clearance for underhood lines. The bar-and-plate intercooler core design is the most efficient available.
Does it work, you ask? Here's one data point: The TurboXS dyno measured a 35 hp increase over the stock top-mount intercooler on a car running race gas and full "Stage 4" mods, and a 28 hp increase with pump gas. Want more proof? How does 11.96 in the quarter mile sound? This intercooler did it.
The Gigantic Top Mount Intercooler bolts directly on your WRX. It comes complete with the cast Y-pipe and matching silicone couplers. Fit under the hood is obviously snug; you may have to bend and/or cushion some underhood lines to because of the tight clearance. Now, works with your stock bypass valve, and the TurboXS RFL or H-BOV. May not work with other manufacturer's blow-off valves.
Now available for all 2002-07 WRX and STi. Comes complete with upgraded silicone Y-pipe.
