Helped me

My car has a finicky catalytic converter. My mechanic recommended this to help get me through inspection. For me, this and a quality air filter eliminated my error codes. Happy with the product

It the real deal, but you must follow the instruct

You must watch the YouTube video that shows running your engine for 30 minutes straight at 3,000 rpm. This heats up the cats to burn out the junk that's accumulated.
