Had a P0420 code on my 350Z (VQ35HR) after installing HFCs. I installed the 90 degree mini catalizador. Cleared the code with an OBDII scanner. After ECU tested the catalytic converters, the code remained gone and car ready to pass the state smog test. Mini catalizador did what it was supposed to do.

They are pure genius! My check engine light went off immediately! A mechanic friend of mine told me about them after he said they never failed him. They replaced having to get a new, pricey catalytic converter. Highly recommend!

Installation took about 15 minutes. Product was of great quality and exactly as advertised. It did exactly what I was hoping it would do. Best 70.00 I've spent in a long time.

Within 24 hours of installation, my 2011 Camaro SS check engine light was adjusted by the ECM and disappeared from the dash. No issues for the past 72 hours. It appears to work as advertised.

I admit I was skeptical, but I was so wrong! This adapter is the real deal. I’d been driving with a check engine light that had a mind of its own. After using this, it feels like my car finally got its act together. Smooth rides with no more worries about sudden breakdowns, and I’ve even noticed a slight boost in fuel efficiency. Count me impressed!

I don’t typically leave reviews, but this spacer truly deserves praise. My car was a wreck—check engine light always on and performance inconsistent. After installing this spacer, it feels like a brand-new ride! Smooth acceleration and no more annoying lights—it's a dream come true. If you’re facing car troubles, invest in this spacer; you won’t regret it!

I encountered a P0420 code after installing some faulty spark plugs that caused misfires. I decided to try this product, but it's essential to ensure everything else in your vehicle is functioning well first. For my setup, the straight design was ideal for the catalytic converter near the firewall, while a 90° would be necessary for front installation due to space. The installation was challenging, but it resolved my issue. Highly recommend!
