Evo 7/8/9 Radiator Hoses & Install Clamps

Evo 7/8/9 Parts
Back to Radiator & Cooling

From a simple, OEM upgrade to custom -AN lines and fittings, STM has what you need! Kits for the 4/5/6 in 7/8/9, Samco colored hoses to match your engine bay, stainless hose clamps and more for the Evolution VII VIII IX models.

Fitment notes for Evo 4/5/6 vs 7/8/9:
The upper Evo 7/8/9 hose is the same and will fit all factory-style 7/8/9 radiators.
The upper Evo 4/5/6 hose will fit the STM Billet Radiator as well as a 4/5/6 radiator in a 7/8/9 and also the STM and Koyo half-sized radiators.
The lower Evo 4/5/6 hose ONLY fits 4/5/6 style radiators in an Evo 4/5/6. It is not compatible with the 7/8/9.
The lower Evo 7/8/9 hoses are slightly different and do call for different factory part numbers, but they will work on all 7/8/9 models. The water pipe is what is different, not the radiator outlets.
Installing an Evo 4/5/6 radiator in your 7/8/9 moves the hose outlet to the right of the engine bay to clear room for a bigger exhaust manifold.
