Catalytic converter cleaner high quality pass emissions test cleans catalyst carbon build-up MotorPower Care

I had an issue with a partially clogged catalytic converter that had been throwing the engine light on. Scanning my Jeep, it had a P0430 code. Using this cleaner was very simple. I added it to a full tank of gas and drove for about 20 minutes. It worked quickly as the engine light went off. Fast forward about 3,500 miles since first using it and still no issues. Now, I plan to use a bottle of this maybe 2-3 times a year as preventative maintenance to keep it as clean as possible. If anyone is running into an issue with a dirty or clogged catalytic converter, it's worth trying this stuff first before spending way more on replacing the converter itself. It can possibly save you a ton of hassles later on.

This product worked for me. I had a P0420 code on my Ford truck and it would not pass emissions test. Put this in about 15 gallons of gas drove 85 miles. Check engine light went off and I passed inspection.

Worked exactly like it should. Noticeable improvement in performance and smoother idle.

I think this will clean out the converter. The idle improved after warming the engine up one time.

Trusted brand. Good instructions. Easy to add to tank

the item works for me it is good at removing carbon buildup

i have two cars that get P0420 every couple of days i followed the directions on the can ,adding to my tanks wirh around 10 gals of gas unfortunately borh cars still get the code worh the same regularity pro the cana were easy to use, and rhe oour spouts were nice

Can’t tell any difference after using this product.

After cleaning, there are even more issues—now there's code P2423! This one doesn't exist!

When I received this, the top had been damaged and the product had leaked. There was still half in the bottle, but the top and the small funnel that came with was damaged. I can’t say if it worked or not. All I can say is that half the treatment done nothing at all. 🤷‍♀️
