Product Details

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 exhaust manifolds. Includes interchangeable fittings for use with factory-style radiator hoses or for -16AN lines.

The billet aluminum top and bottom tanks look amazing in the engine bay. This design places the radiator hose bung to the right of the engine bay, clearing room for larger manifolds. Two screw-in fitting styles are included for use with either OEM style hoses or -16AN fittings and line.

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.

Includes:

• Radiator
• Fittings for OEM Hoses
• Fittings for -16AN Line
• Extra Fittings (note, two small fittings will not be needed for Evo)
• Mounting Hardware for A/C Condenser:
• (2) M6x20 Stainless Bolts (MS2550020A20000)
• (2) M6 Stainless Nuts (MN2550000A20000)
• (2) M6 Stainless Fender Washers (WC6360000A20000)

⚠ Fitment Notes

• Does not fit with factory air box
• Requires Evo 4/5/6 upper hose or -16AN fittings and line
• Must remove rubber bushings in A/C condenser
• Requires radiator cap relocation
• The top tank does not have a port for a radiator cap. You will need a STM Water Neck for Radiator Cap Relocation. They are sold separately as they are different for Evo 7/8 or Evo 9 models. This places the radiator cap at the highest point in the cooling system. Also it looks awesome. v
• Drain Bung:
• This radiator does NOT have a drain bung.
• A/C Condenser Adjustment:
• If you still have A/C, the condenser needs to be adjusted forward for a proper fitment. There are two mounting bolts on the top ends of the condenser. Remove the spacer and bolt it back in place using the included stainless hardware. This allows the condenser to sit forward another 1/4 inch. The car pictured has A/C, as installed.
• Suggested for Install:
