Frequently asked questions

Is this genuine Koyo?

Yes. As an authorised Koyo dealer we supply genuine Koyo parts, new and not replicas.

Will an aluminium radiator run cooler?

An aluminium performance radiator has more cooling capacity than a tired factory unit, which helps on track and in traffic. Choosing the right core for your use matters, so tell us how you drive the car.

Is it a direct fit?

Most Koyo radiators are designed as a direct fit for a specific car, though some need a particular cap or minor fan shroud work, which is noted per part. We can confirm for your car.
