Coolant Reroute Kit, MX5 Mk1 1.8 & All Mk2/2.5

Developed by IL Motorsport, this high quality reroute kit is the perfect answer to the poor coolant flow problem. Mazda's "in the front out the front" approach means that cylinder number four is never properly cooled. This uneven temperature can cause all kinds of issue such as premature engine wear, carbon build up, failed piston rings, and incorrect emissions readings.

Well, not any more! This kit converts the engine so the coolant flows in through the front of the engine and out through t back, resulting in all four cylinders being cooled to the same temperature. Even in high load situations the temperature stays stable and in turn helps keep the oil temperature more stable. Also, because of the more consistent temperatures the engine management receives more accurate air fuel mixture data which is particularly important for forced induction engines.

The kit is supplied with everything you need including fitting instructions. It even has the positions for the temp sensors in the same place so there is no need to extend any wiring.
