Description
The Mishimoto J-Line Intercooler (MMINT-UJB) is a compact, high-capacity front-mount intercooler engineered to handle up to 500 horsepower without demanding the front-end real estate of a full-size core. Mishimoto tested the J-Line on the highest-horsepower Hyundai Genesis Coupe in the world, proving that this smaller cooler can pack a big punch even under serious boost. Built from 6061 aluminum and TIG welded to perfection, the J-Line is engineered for enthusiasts who need forced induction cooling performance without sacrificing clearance.
As a dedicated forced induction upgrade, the J-Line intercooler relies on a bar-and-plate core to maximize heat transfer, effectively reducing intake air temperatures so your engine’s induction system can make consistent power run after run. Its compact footprint makes it a smart choice for a forced induction system on cars with limited front-end space, since in most instances the J-Line allows you to run more power while preventing you from having to remove your crash bar – a rare compromise in the world of performance induction. Whether you’re chasing a modest bump in output or building toward the 500HP ceiling this core is engineered for, the J-Line’s bar-and-plate design and 2.5-inch inlet and outlet are built to deliver the flow and volume that serious forced induction setups demand.
