Billet Aluminum Slim Radiator

Mitsubishi Evo 7/8/9

The STM Billet Aluminum Slim Radiator for the Evo 7/8/9 models features a streamline billet aluminum top and slim design. The upper radiator hose fitting is located to the right of the engine bay, making room for larger or ‘forward facing’ exhaust manifolds. Includes interchangeable fittings for use with factory-style radiator hoses or for -16AN lines.

This radiator does not have a bung for a radiator cap and will utilize the STM Water Neck for Radiator Cap Relocation moving the cap to the highest point in the cooling system. Perfect fit to the factory mounting points and won’t stretch out your bracket bushings. This radiator also does not have a drain port. The radiator with fittings weighs 11.85 pounds.
