Has anyone tried the catalytic cleaner stuff, such as "guaranteed to pass"?? Is it safe for the rotary engine??

Thanks!

 

i wouldn't put that stuff in my car, but its up to you.. I kinda doubt that its good for the rubber and teflon seals in the engine. If you just failed e check or something, you may as well get new converters, you'll notice a good increase in power. I got the bonez superflow from rx7.com and am pleased with it.
