Mishimoto’s oil cooler kit for 2004–2006 Pontiac GTO (5.7L/6.0L) provides a front-sump DIY option for LS1/LS2 builds. The 25-row cooler features a CNC-machined oil line adapter for AN fittings and requires custom bracket fabrication for installation. In testing the kit lowered oil temperatures by roughly 65°F, making it appropriate for race or heavily modified applications that need substantial oil temperature control.
