What Guaranteed to Pass Users Say

"This Stuff Works."

This stuff works. I live in NJ where we have very stringent emissions testing and I have used this product 3 times in the last six years. Same car now with 140,480 miles on the clock and readings were about 40% of what is allowed, follow instruction on the box and you got it.

"I Didn't Just Pass The Test I Smoked It!"

Failed 5 times in one day and then pasted after one tank full, man this stuff works. My old 83 Dodge truck has been a pain! Even my main man hates my truck but he always come through with a passed AZ air tag. Just read the box and follow the directions. I didn't just pass the test I smoked it! CO2 was like zip!

"This Product Saved Me Several Times Already."

Excellent product, I got "Check Engine" light, and my mechanic suggested I replace catalytic converter (about $1,000 job) before I go for inspection. A friend of mine recommended I buy "CRC Guaranteed to Pass" formula. I bought it, followed instructions, and passed NJ State Inspection with high score. I have more than 180K miles on my car, and this product saved me several times already. I would strongly recommend this product to my friends.
