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

If you're pushing your 2004-2006 Pontiac GTO, especially with the 5.7L or 6.0L LS engine, you know that high oil temperatures can be a real problem. This Mishimoto thermostatic oil cooler kit is designed to tackle that head-on, ensuring your engine oil stays within its optimal operating range. It features a substantial 25-row stacked-plate cooler, which is Mishimoto's largest, built to handle the demands of these powerful engines.

Because space is tight around the oil filter housing on the GTO, a traditional thermostatic sandwich plate isn't an option. Instead, Mishimoto developed a unique in-line oil thermostat. This unit mounts neatly under the headlight with a custom bracket and works to maintain a consistent oil temperature of around 185F. During testing, without the thermostat regulating flow, the kit demonstrated an impressive oil temperature reduction of 65F, showcasing its significant cooling capacity. The kit also includes a specially designed adapter that bolts to the oil filter housing, allowing for the connection of the stainless steel --AN oil lines.

This kit comes with the Mishimoto Lifetime Warranty, giving you peace of mind that your engine is protected. While the thermostat is designed to keep oil at 185F for optimal performance and longevity, the raw cooling power of the 25-row cooler is evident from the substantial temperature drop measured during testing.
