Koyo Racing Aluminum Radiator - Evo 4/5/6 (Fits 7/8/9)



Fits these Applications:
2001-2006 Mitsubishi Lancer Evolution 7/8/9 (With 4/5/6 Upper Hose)
1996-2000 JDM Mitsubishi Lancer Evolution 4/5/6 (Factory Replacement Fit)


Install Notes:
The Evo 4/5/6 Radiator fits the Evo 7/8/9 and puts the upper coolant hose in a different location, creating extra room for exhaust manifolds.

You will need the Evo 4/5/6 upper radiator hose if you are swapping it into your Evo 7/8/9.

Your factory-style lower hose will still work. The lower hose is vehicle-specific no matter which radiator you have. If you have an Evo 8, use the Evo 8 style lower hose. The radiator outlets are the same, but the water pipes are different between the models.

This will not fit with the Factory Evo 7/8/9 airbox.

Koyo Radiators provide 20% to 30% more cooling than standard radiators, handle high revving, high performance motors - perfect for Turbo Charged engines. Made from aircraft quality aluminum and Heli-arc welded, cores are NOCOLOK-brazed.

Good product!

Satisfied with the purchase.

The good:
The customer service was pretty good and quick to reply as far as answering some of the questions I had prior to purchasing it. Shipping/ tracking was very good and arrive as scheduled. The packaging was also pretty good, there was a couple of fins that got bent not sure if that’ll affect anything except the look.
The not so good:
Kind of had me a little worried because it wasn’t exactly a direct fit per described/ answered. A pair of mounting brackets didn’t line up, not the same as the stock rad, had to modify the fan/ remove and relocate brackets on the fan to actually have it line up with each other...
Overall I’m pretty satisfied. I would purchase again from this company and will be looking for sales and discount. Thank you.
