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!

Excellent Products!

I am so impressed with your products--nothing has worked to rid my car of the dreaded CEL light until now. I ordered the mini-cat 45-degree sensor spacer, and the 90-degree. Product is wonderfully well-built, and totally adjustable for fit. I found the 45-degree cat spacer fit best for my extremely tight space (2016 Cadillac ATS). Love how it fits, and how it works--no more CEL light!! Thank you for your fine products--you are an amazingly good company in a sometimes-shifty industry. I am very grateful for you!!

Mini Catalizador O2 Sensor Spacer CEL FIX P0420/P0042/P0430 Code Universal (Straight)

Impossible made possible

I was working on a 2004 Honda. Accord that wouldn't pass smog. the car came to
me in poor running condition. It had no power. To take off from a intersection you needed a head start. I discovered that the converter was plugged almost solid. I decided to cut a small hole to see if it ran better and it did. I gutted the cat and put it back together and it ran great. Now my thoughts were to buy a universal cat and be done with it. Well that did not go as planned because the state I live in banned universal cats for import cars and you had to get it from the dealership and the dealer wanted almost $2000 I was searching the net and ran across the Mini cat. I did not think it would work. But what the heck it's worth a shot so I ordered it. The cat was just a shell after I gutted it. I put it on and decided to try smogging the car. Well to my surprize the car passed smog Thanks to the Mini Cat....

Couldn’t pass inspection

I was so skeptical that these would actually work, but they do!!! Fairly easy to install when you have the right tools. Had p0102, p0430, and p0420. All codes have cleared and not returned

No CEL

Does what it was intended to do. I wanted to avoid the dreaded CEL when removing the CAT. It did. Been driving and no errors what so ever. Just what I wanted and needed. Works as designed. Would definitely recommend this product.

Worked perfectly

Excelente producto

Llego rápido y funcion muy bien

Magic stick

Great product, even better idea for how the product works .I can't believe how such a simple thing can save me so much money, my car is a bmw.They wanted 8000$ to fix my cats and the cheapest place I found was 2500$ and my cats show no problems car driver great no smell from cats or any symptoms just a stupid light that causes so much trouble, so you decide what is the better deal 20$ or 2500$ not hard to figure out why I chose mini cats unless you have money to just burn or throw away I think you would be smart enough to purchase mini cats,well made quality product too not just a dung you have to weld on,if you have a cat light on,just choose mini cats and you will see what a great deal and feeling it is when that little sinister light goes away. Thanks mini cats!

GX470 fix

Worked perfectly to fix Cat code on 2003 GX470.

Cool design

It worked

After installing it, I feel that the air-fuel ratio readings fluctuate a lot. Is this normal?

Works so far

I installed this on my son's 2012 Honda Accord after getting code p0430. He's driven it a couple hundred miles and the CEL is still off. Hopefully the CEL remains off.
