Thank you. You have rated this product.

Koyo designs its radiators to take all factory spec parts which means your factory cap will fit, and your factory plug will fit, and your factory fans will bolt right on.

But for those who want an upgraded new cap to go with their new Miata Koyo Radiator...or stock you go.

Koyo Racing 1.3 Bar Hyper Red Radiator Cap raises the cooling system pressure to 1.3 bar to improve entire cooling system flow. The higher pressure cap reduces the chance of air from entering the system compared to the factory cap. It also improves the look of your engine bay.

Thanks for making this work and providing great customer service! I had a full weekend with the install, but man was it worth it. The flywheel was such a good choice. I can't believe how much easier rev-matching down shifts are. The ACT is surprisingly easy to live with, even with the engagement point very low. I'll tackle that when it stops raining. Thanks again for making this happen this weekend.
