Mishimoto 2018+ Kia Stinger GT 3.3T Performance Intercooler Kit - Black

If you're looking to get the most out of your 2019-2025 Genesis G70, especially the 3.3T engine, this Mishimoto Performance Intercooler Kit is a solid upgrade. The stock intercooling system can become a bottleneck as you push your car harder, but this kit replaces the entire setup from the turbos all the way to the throttle body. Mishimoto has swapped out the factory tube-and-fin core with a much more robust bar-and-plate design, which is TIG-welded to cast aluminum end tanks. This construction is key for better heat dissipation and improved airflow compared to the stock plastic end tanks.

You'll notice a significant increase in core volume, up by 94 percent, and a 74 percent larger external fin surface area. The piping has also been upgraded, keeping the aluminum construction but increasing the inner diameter to 3 inches to allow more air through with less resistance. Even the piping merger manifold has been improved, with larger inlets and a 3-inch outlet, boosting flow by 51 percent right from the turbos. This kit is finished with a micro-wrinkle black powder coat for an OEM+ look and uses 5-layer silicone couplers to connect everything. On the dyno, this kit showed a 29-degree F drop in outlet temperatures and an 8 whp and 8 wtq gain on stock tuning, with even better results when paired with a tune.

This kit includes the performance intercooler, all necessary piping, the cast aluminum merge manifold, and the silicone couplers to get it all connected. It's designed as a direct replacement for your factory intercooler system, making installation more straightforward. You'll be able to retain your stock recirculation valves with this setup.
