Where can I purchase?

Unit won't power on? LED light not lit up.

All Max Cylinder Disablers go through multi-point inspections including 100% end of line tested. If the product has a SN# label on the top, it passed inspection and worked. If you are not getting an LED light, verify your fuse to your OBD port is providing power, and that your terminals on your OBD port are not corroded. If you find corrosion, contact cleaner or rubbing alcohol will clean then.

Contact us if you have any questions or would like to verify your VIN number for fitment.
