DEI NC transmission tunnel heat shield kit

A common problem with the Miata is heat transferring through the tunnel and into the passenger compartment. To help mitigate this, the NCs came with a shield installed from the factory inside the tunnel, but it is typical to find these shields missing or in pretty ragged condition now that NCs are nearly two decades old. DEI now offers a solution to replace the stock NC shield with an improved shield that dramatically reduces heat transfer and provides some noise insulation.

The precision cut kits are constructed of an embossed ten mil aluminum face bonded to a 1/8" thick composite glass-fiber core able to withstand up to 1750°F. The multifaceted aluminum skin offers improved reflection and rigidity while remaining incredibly lightweight. The super strong high-temp pressure-sensitive adhesive backing can hold past 450°F and withstand harsh road conditions, including water, wind, and debris. The multi-piece design makes the installation easier and possible without removing the transmission.
