Description
The Mishimoto Performance Intercooler Kit, part number MMINT-STNGR-18BK, is a complete turbo-to-throttle-body overhaul of the factory forced induction system on the Lambda II GDI 3.3T. Mishimoto tossed the stock tube-and-fin core and plastic end tanks in favor of a bar-and-plate core TIG-welded to cast aluminum end tanks, then reworked every pipe and coupler in between for a genuine performance induction upgrade rather than a cosmetic swap.
This kit exists because the factory intercooling system was identified as a bottleneck on an otherwise strong platform, so Mishimoto engineered a forced induction turbo cooling solution built around a 94-percent larger core volume and a 74-percent increase in external fin surface area. The aluminum piping keeps a factory-style look but grows to a 3-inch inner diameter for improved flow with minimal pressure drop, and the hot-side piping merger manifold was reworked with 2-inch inlets and a 3-inch outlet for a 51-percent increase in flow straight out of the turbos. On the dyno, that translated to a 29-degree F drop in intercooler outlet temperature and gains of 8 whp and 8 wtq on stock tuning, with a stage 1 map tune pushing the temperature drop to 41 degrees F and adding another 6 whp and 8 wtq on top of the tune. Every piping section is finished in a micro-wrinkle black powder coat and linked with 5-layer silicone couplers, and the whole induction system remains compatible with the stock recirculation valves.
Vehicle Applications
This is a specific-fit forced induction upgrade, not a universal part. It is designed for the 2018-2023 Kia Stinger GT, Kia Stinger GT Limited, and Kia Stinger GT2, as well as the 2018-2022 Kia Stinger GT1, the 2022-2023 Kia Stinger GT Elite, the 2019 Kia Stinger GTS, and the 2023 Kia Stinger Tribute Edition. It also fits the 2019-2025 Genesis G70, sharing the same Lambda II GDI 3.3T engine and CK chassis code as the Stinger GT. Installation requires permanent modification to the front air guide shrouding, part number 29135-J5000.
