The Miata was not designed for superchargers and adding a big air to air intercooler is the best way to lower the intake charge and prevent detonation that can destroy your Miata motor. Enter the Track Dog Racing intercooler system for the JRSC M45 supercharger. We use the same in our supercharged Miatas and it works much better than any other Miata supercharger system we have tried. Includes very large front mount intercooler that makes your Miata run faster and look more aggressive, mounting hardware and detailed instructions for installation on your Miata. Ships in 1 to 2 weeks direct from the maker.
