This HKS unit is 100mm thick and 142mm tall against a stock 112mm, which works out to substantially more core volume in the same front-mount position. More volume means charge air arriving cooler and staying cooler through repeated pulls.\u003c\/p\u003e\n\n\u003ch4\u003eHatchback Only\u003c\/h4\u003e\n\n\u003cp\u003eThe fitment gate on this page, so confirm before ordering.\u003c\/p\u003e\n\n\u003cp\u003eThis fits the \u003cstrong\u003eFK7 five-door hatchback only\u003c\/strong\u003e.

If you're in a two-door or four-door, this isn't your intercooler.\u003c\/p\u003e\n\n\u003ch4\u003eWhy The Factory Unit Runs Out\u003c\/h4\u003e\n\n\u003cp\u003eThe stock intercooler is adequate for a stock car being driven normally. It stops being adequate in two situations.\u003c\/p\u003e\n\n\u003cp\u003eThe first is heat soak. An intercooler that can't shed heat fast enough lets intake temperatures climb, and when they do, the ECU pulls timing to prevent knock. You lose power, and you lose it progressively. Full power on the first pull, noticeably less by the third or fourth.\u003c\/p\u003e\n\n\u003cp\u003eThe second is added boost. Tune the car and you're pushing more air through the same core, which means more heat to reject through a unit that was sized for factory output.\u003c\/p\u003e\n\n\u003cp\u003eEither way the intercooler becomes the limiting factor, and no amount of tuning works around a saturated core.\u003c\/p\u003e\n\n\u003ch4\u003eNearly Double The Thickness\u003c\/h4\u003e\n\n\u003cp\u003eThe numbers make it clear.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHKS core:\u003c\/strong\u003e 710 x 142 x 100mm\u003cbr\u003e\n\u003cstrong\u003eFactory core:\u003c\/strong\u003e 60mm thick, 112mm tall\u003c\/p\u003e\n\n\u003cp\u003eGoing from 60mm to 100mm thick and 112mm to 142mm tall gives you considerably more surface area for heat transfer. That's the whole mechanism: more surface area means more heat leaving the charge air before it reaches the engine.\u003c\/p\u003e\n\n\u003cp\u003eAnd it mounts in the factory front position as a direct replacement, so you're not relocating anything or cutting up the front of the car.\u003c\/p\u003e\n\n\u003ch4\u003ePiping Is Included\u003c\/h4\u003e\n\n\u003cp\u003eThe kit comes complete with the core, inlet pipe, outlet pipe, and hardware.\u003c\/p\u003e\n\n\u003cp\u003eThat matters because a larger core needs piping that mates to it properly. Buying a core alone and adapting factory pipes is where fitment problems come from, and HKS avoided that by supplying the whole charge path.\u003c\/p\u003e\n\n\u003ch4\u003eSort The Whole Airflow Path\u003c\/h4\u003e\n\n\u003cp\u003ePractical ordering advice for anyone building out an FK7.\u003c\/p\u003e\n\n\u003cp\u003eAn intercooler handles the charge air temperature, but it's one section of a path that runs from the filter to the throttle body.

Tuning a car with a saturated intercooler means the tuner is working around a heat problem rather than around the engine, and you'll end up leaving power on the table or revisiting the tune after you fix the cooling.\u003c\/p\u003e\n\n\u003cp\u003eSort the airflow, then tune.
