Product Description

The Mishimoto MMINT-STNGR-18SL Performance Intercooler Kit is a direct-fit cooling upgrade designed for the 2018-2023 Kia Stinger GT (and variants including GT1, GT2, GTS) and 2019-2023 Genesis G70 3.3T models equipped with the 3.3 L twin-turbo V6 engine. Replacing the restrictive stock intercooler and piping, this kit features a robust bar-and-plate aluminum core with a significantly larger cooling surface and volume, providing superior heat rejection and charge air cooling under spirited driving or on-track conditions. Compared to the OEM system, the Mishimoto intercooler delivers up to ~94 % more core volume and ~74 % more fin surface area, resulting in noticeably cooler intake air temperatures and reduced pressure drop through the intercooler.

Upgraded 3" intercooler piping and a high-flow merger manifold help increase airflow by ~51 % over stock, and the inclusion of a methanol injection bung on the cold-side pipe enables flexible tuning options for advanced setups. Dyno testing has shown a ~29 °F reduction in intercooler outlet temperatures on stock tuning and up to ~41 °F with a stage 1 map tune, along with measured gains of ~8 whp and ~8 wtq. Compatible with stock recirculation valves and most aftermarket intake systems, the MMINT-STNGR-18SL is ideal for enthusiasts seeking improved heat management and performance consistency across daily and high-load driving scenarios. Supported by Mishimoto's Lifetime Warranty, it's a high-quality choice for maximizing the performance of your 3.3T Stinger or G70.
