Show original supplier description
The Improved Racing EC6-600 Performance Oil Cooler Kit is a direct bolt-on upgrade for 2005-2013 Chevrolet Corvette C6 models. This kit is essential for track use, where oil temperatures can reach up to 300°F with the factory Z06 setup. The EC6-600 is designed to lower peak oil temperatures by 30-50°F, helping to prevent engine damage and oil starvation. The kit includes an EGM-112 thermostatic oil cooler adapter, which helps regulate oil temperature and accelerates engine warm-up, making it suitable for both street and track driving. The adapter also features a 1/8" NPT sensor port for the installation of aftermarket oil temperature or pressure sensors. The oil cooler itself is a high-efficiency, 45-row, triple-pass unit that utilizes the factory mounting points in the radiator shroud. Minor cutting of the factory radiator shroud is required for installation, with a laser-cut acrylic template and instructions provided for a precise fit. Professionally assembled -10AN oil lines are included, featuring a Viton rubber interior, stainless steel reinforcement to prevent kinking, and a silicone-fiberglass sleeve for protection against header heat. The lines are lightweight and have hard-anodized aluminum dual swivel fittings. The thermostat is available in three temperature ratings: 180°F (recommended for street use and wet sump vehicles), 200°F, and 212°F (recommended for race cars using higher viscosity oil and needing to maintain higher minimum temperatures). Installation notes indicate that the oil cooler can be mounted in the factory Z06 location, at an angle, or flat in front of the radiator. Mounting in the factory orientation may sometimes lead to elevated coolant temperatures due to insufficient airflow; this can be resolved by angling the cooler or mounting it flat, though custom brackets and modifications to the undertray may be necessary for flat mounting. The kit comes with a Lifetime Warranty and is Made in the USA.
