Mishimoto 05-06 Pontiac GTO Performance Aluminum Radiator

When you open the hood of your 2005 or 2006 Pontiac GTO, you'll find a Mishimoto Performance Aluminum Radiator, a Mishimoto Magnetic Oil Drain Plug, and a Mishimoto 1.3 Bar High-Pressure Radiator Cap. Stock plastic radiators can be a weak point, especially with the heat generated by the GTO's 6.0L engine. This Mishimoto radiator is built to handle that heat, keeping your engine running cool whether you're on the street or the track.

This radiator is constructed from all-aluminum with TIG-welded end tanks, which helps it dissipate heat much better than the original plastic unit. It features a robust, two-row brazed aluminum core that increases coolant capacity by 0.64 liters. This improved capacity and core design work together to lower coolant temperatures by a proven 15 degrees Fahrenheit. It also includes an in-tank transmission fluid cooler that works with your stock lines, making installation straightforward. The included magnetic oil drain plug is a nice touch, helping to catch any stray metal fragments in your coolant system, and the high-pressure radiator cap raises the boiling point of your coolant for added safety and efficiency.

With its increased capacity and improved heat dissipation, this radiator is a solid upgrade for any GTO owner looking for better cooling performance and long-term reliability. It comes backed by Mishimoto's Lifetime Warranty, so you can be confident in its craftsmanship.
