Very Pleased

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.

Absolutely Works

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! They are pure genius! My check engine light went off immediately! A mechanic friend of mine told me about them...

Engine light be gone

I was troubled with a p0430 code for years. Installed this on bank 2 sensor 2 and boom code has not came back! Much cheaper than a catalytic converter. I was troubled with a p0430 code for years.

Great quick

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 admit I was skeptical, but I was so wrong! This adapter is the real deal. I’d been driving with... I admit I was skeptical, but I was so wrong! This adapter is the real deal.

Save on catalytic converters

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 don’t typically leave reviews, but this spacer truly deserves praise. My car was a wreck—check engine light always on...

G45 - 2025 BMW X3 M50 xDrive

Installed Burger Tuning JB4 Pro, I did change the downpipe out for one from BimmerNetwork for a catless and then added the Mini Catalizador O2 Sensor Spacer CEL FIX P0420/P0042/P0430 Code Universal (90 Degree) to help with the CEL, lastly installed the CTS turbo intake system. In all this combination I have insane power at my feet and no CEL!! Worth the buy and can’t thank these guys enough for their efforts! The adapter is installed at the downstream o2. Chassis information is G45 - 2025 BMW X3 M50 xDrive - B58 Gen 3 engine.

No more check engine light

My grandson helped me install this on my 08 Ram. He said, Pops, this is the hack all the car guys use.' Sure enough, no more check engine light during my road trip! Simple but effective.

My check engine light hasn't come on since I installed this adapter. Pure magic!

Smooth performance, no more lights!

These adapters are a game-changer! My car's check engine light was driving me crazy, but after installing these spacers, it's like a weight has been lifted off my shoulders. Smooth performance, no more lights!

Great Buy

The part works great, just as described. Shipping was fast and my check engine light went away.

I'm very pleased with this choice!

This accessory is definitely worth the value! The material is incredibly robust and feels reliable in use. The results after installation were impressive.

Worked great!!!! Very satisfied

These worked great!!! No more check engine light. Would definitely recommend buying them

Very easy!

Installation was so easy, even I could do it. Huge thumbs up from me!

It worked!!

I could not for the life of me get my check engine light to go away . I tried cat cleaner , 2 other spacers and nothing worked! . I did not want to put in a brand new cat. After I put this little magical gadget it and im pleased to say I passed inspection today! Im so so so happy I found your company. Thank you so so so much! Very satisfied customer!

Finally a working solution!

I have used several different O2 defoulers in the past, and have even had some of them modified, with no success. After 5 of 6 times back to the muffler shop (including the expenses every time to have them do work), I installed this one. So far, several hundred miles and no more CEL! If you are getting a CEL due to a modified exhaust, I highly recommend this product!

I wish I had discovered this sooner. My car feels like new again!

I'm very pleased with this spacer

It did a great job extending the O2 sensor and eliminating the error code. Solid product and definitely worth the investment.

Works Like Magic!

Installed the spacer and instantly saw results. My car feels more responsive, and the check engine light hasn't bothered me since. Couldn't be happier with this purchase!

Quality Product!

The build of this spacer is top-notch. Installed it myself in minutes, and my check engine light hasn't come on since. Highly recommend!

Worth Every Penny!

This spacer is a game-changer. No more stressing over check engine lights. My car's performance has improved noticeably. Thank you, Mini catalizador

Great Solution!

Bought this spacer after trying various other fixes for my check engine light issue. Finally found the perfect solution. Couldn't be more satisfied!

Amazing Product!

Installed the spacer without any issues and saw immediate results. My car feels like new again. Five stars all the way!

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

It's like having a mechanic in your glove compartment. A must-have for any car owner.

Say goodbye to expensive trips to the mechanic. This adapter saved me tons of money on diagnostics.

I was skeptical at first, but this little gadget exceeded my expectations. My car's performance has noticeably improved.

Installation was a breeze and the results were instant. Can't recommend it enough!

I bought the mini-cat to help pass PA emissions

I bought the mini-cat to help pass PA emissions with an aftermarket downpipe( catted) that before-hand I had secondary 02 disabled via tune bc it popped a code. Upon installation I re-enabled secondary 02, and with a cheap scan tool cleared the p0420 when it came back 2 days later… fast forward I pulled the battery to do a whole system reset of all the sensors.. 250 miles and 10 days later and no check engine light, and all of my sensors so readiness on a scan tool

Best gadget ever

When the check engine light popped on, I was frustrated. This product kept coming up as a recommended fix. After trying it, the code hasn’t come back for weeks. It’s such a simple fix for such a big headache.
