HAVE VEHICLE MODS? GET A TUNER KIT!

If you have, or plan to add in the future, other vehicle modifications, like experimenting with alternative fuels such as race fuel, E85 fuel, and methanol supplemental fuel, or changing engine components like heads, headers, exhaust, and cams for the engine, then a Tuner Kit is the best option for you. These kits make sense for someone wanting to perform custom tuning of the car and push the envelope in performance.

Tuner Kits are identical hardware to full systems, except they do not include tuning or fuel components. Tuner kits are highly customized by the end user and are, therefore, not emissions certified.

ABOUT STREET LEGAL SUPERCHARGER SYSTEMS

If you live in a state with emissions regulations and your build is for street use, then you need a street legal system. Specific to the 2018+ Mustang, ProCharger offers two street legal system options - an HO and a Stage II. Both systems retain the factory airbox and use the factory 6-rib belt. The power levels are equivalent to the non-street-legal systems. All our street legal systems have an associated CARB EO# for compliance.

Tuner kits for this vehicle are NOT legal for street use in California. These products are intended for racing or off road applications only.
