Koyo HH Series Aluminum Radiator for Mitsubishi Lancer Evolution 4, 5 and 6 requires use of Evo 8 radiator fan or an aftermarket slim fan.
Perfect upgrade when looking for that extra cooling! Purchase a required Slim Fan to go with it and keep those temps down! Evo VII - IX owners can benefit from this Radiator to bring the upper rad hose further from those tubular manifolds!
