Mishimoto 04-06 Pontiac GTO 5.7L/6.0L Oil Cooler Kit - Black

This Mishimoto oil cooler kit comes with a 25-row cooler and a CNC-machined oil line adapter ready for your custom setup. It’s designed for LS1 and LS2 engines with a front-sump oil pan, like the ones found in your 2004-2006 Pontiac GTO. This is a DIY kit, meaning you’ll need to fabricate custom brackets to mount the cooler where you want it, giving you flexibility for highly modified vehicles.

The main goal here is to keep your oil temperatures in check, especially when you’re pushing your GTO hard. During testing, this kit dropped oil temperatures by a significant 65 degrees Fahrenheit. That kind of cooling is crucial for drag vehicles, particularly those running turbochargers or superchargers, where oil breakdown can happen quickly under extreme heat. The included adapter makes it easy to connect your own --AN fittings for a clean and reliable oil line setup.

Because this kit requires custom fabrication for mounting and is intended for race applications, it's best suited for dedicated track or drag cars. If you're building a serious performance GTO and need robust oil temperature management, this Mishimoto kit offers a solid foundation for your custom cooling solution.
