Coolant Reroute Kit, I.L Motorsport

The MX-5 engine was originally designed for a front wheel drive car, which means Mazda had to move a lot of stuff around to make it fit a rear wheel drive configuration.

One of the changes they made was where the coolant exits the engine, moving it from the rear of the engine, to the front. This set up is great from a packaging perspective, but it's not ideal for allowing the best possible path for the coolant to follow, meaning that cylinder 4 is typically a 'hot spot'.

The I.L. Motorsports coolant reroute kit fixes this issue by moving the coolant exit to the back of the engine (where it was supposed to be in the first place). This means lower and more consistent coolant temperatures over the stock system, essential for high power, or boosted cars.

Includes a cast aluminium remote thermostat housing, a custom silicone coolant hose and a custom guide for the extra long hose.
