90-05 Mazda Miata Coolant Reroute Kit *Now shipping the Version 2 ***
Use this spacer to reroute the coolant outlet to the rear of the cylinder head and eliminate the factory hot spots found in the rearmost cylinders. MAKE SURE to pair this with our Coolant Block Off Plate to eliminate the factory outlet at the front of the cylinder head or factory water neck. These are listed on our other items for sale.NOTE: Installation is tight, but can be done with the engine installed, but we prefer to do it with the engine out.
*The version 2 spacer is a bit thicker for ease of install, and a better fit. Thanks for the response!*
NOTE: 1.6L engines will require accessory port to be tapped for that engines coolant temperature sensor. This spacer will not be plug and play for that application.
NOTE: You will need a block off plate for the front of the engine. These parts are sold separately and available in our store.
