Product Description
The Koyorad HH-Series radiator features a 48mm core and polished aluminum finish. This is a direct replacement fit for the Evo 4/5/6 models. The Evo 7/8/9 models can use this radiator if you purchase an Evo 4/5/6 style upper hose. This 4/5/6 radiator places the hose more to the left of the engine bay, making room for larger manifolds.
Vehicle Fitment:
Fits Evo 7/8/9 with 4/5/6 upper hose
Fits Evo 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.
EVOLUTION 4/5/6, but must use Evolution 7/8/9 fan. When installing in an Evolution 7/8/9, stock fan will mount, but stock air intake system is not compatible.
This will not fit with the Factory Evo 7/8/9 airbox.
Includes:
(1) Radiator
Please note, The Radiator Cap is sold separately.
