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 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

Wanted to say thanks. The exhaust system fit perfectly, no drone at steady throttle, but a nice sound winding thru the gears. And it does sound a lot like my old Alfa. The Racing Beat lowering springs are just right. Appreciate the tech advice and the service.

Purchased the RS Max Power header and midpipe. THESE ARE TRUELY A WORK OF ART! CRAFTMANSHIP IS TOP NOTCH!! SITE PICS DO NOT DUE JUSTICE TO THESE ITEMS! I recommend Brian's site to ANYBODY with a Miata/MX 5. Brian and Co have taken a great automotive platform and elevated it to it's FULL POTENTIAL!
