Performance Radiator Coolant Reroute Kit 1.6L Mazda Miata MX5

Bull Boost Performance
$199.95
| /

The Bull Boost Performance system returns the coolant flow path to the correct configuration used before the Miata came along. In addition, the kit retains full functioning of the original system including correct sensor locations for the stock ECU, heater, bypass circuit operation for proper warm-up and cold over-pressure protection. 

Attention 01-05 owners: Mazda changed the head gasket design for these years to restrict flow to the #1 cylinder. Not a real fix but it does allow the 01-05 to run a tiny bit cooler than the previous years. Because of this change some people thought the coolant reroute can cause uneven cooling in the cylinder head. Through our experience and testing of this kit on 01-05 Miatas, both on the street and on the track, we have not seen any adverse effects from using this kit on any of the 01-05 cars, and have seen nearly all the cooling benefits experienced on ’90-’00 cars. If you have reason to replace the head gasket on your 01-05 engine, consider using a 94-00 head gasket.
