The B series engine for the Mazda MX-5 was originally engineered to be mounted transversely for use in front-wheel-drive cars. This meant there was space for the coolant to enter the head on one side and exit from the other. When repurposed for the MX-5 the engine was mounted longitudinally so that it could drive the rear wheels and placed as far back as possible against the firewall to improve weight distribution.

This left very little room which would make servicing the cooling system difficult. Mazda moved the outlet from the back of the head to the front, which simplified the route the cooling pipes would otherwise need to take. The downside of this is that the rear of the head does not cool as efficiently as the front, leading to overheating even on standard MX-5s.

The Supermiata Qmax reroute moves the outlet back round to the rear of the head, providing a much more efficient path for the coolant to flow around. The outlet is internally machined and radiused to maximise the coolant velocity, ensuring coolant flows freely as it leaves the head. The Qmax reroute has been proven on Supermiata’s 440whp two-time Superlap Battle winning race car, and can comfortably handle the cooling demands of even the most extreme Mazda MX-5s.

Making a warranty claim

Proof of purchase receipt showing the date of purchase, proof of mileage at installation, proof of current mileage and invoice of the work undertaken by an independent experienced professional mechanic must be supplied along with the returned products for a warranty claim to be considered. If your vehicle needs to be used whilst your warranty claim is considered replacement parts from the same manufacturer should be purchased through BOFI Racing. In the event of a successful warranty claim, we will refund the card that was originally used to purchase the replacement parts, in full or in part depending on the nature of the claim. BOFI Racing reserves the right to make full or partial compensation at its sole discretion depending on the condition and mileage use of the returned suspect parts. For example, if you have used the part for several thousand miles before a defect is noticed, only partial compensation may be offered.
