Outstanding!

I’m gonna keep this simple, being an ex mechanic and old Street racer of the 1970s and early 80s. It fixed my problem. 2005 Toyota Tacoma having an intermittent problem with my bank 2 side converter it fixed the problem! $44 is far better Than thousands of dollars for converters. Thank you so much. I’m gonna keep this simple, being an ex mechanic and old Street racer of the 1970s and early 80s. It...

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...

Fixed it

This product is of nice quality, it fit perfectly, and so far no CEL light in 2K plus miles

O2 Sensor Adapter

Adapter is very good quality, heavy duty.

Good

I am driving free of a check engine light, the product works great 👍

Great fast. Shipping

Great fast. Shipping

Works great!

I have a 260k 2015 escalade and was getting codes p0420 and p0430 these and new rear oxygen sensors no more codes! great mini cat if your factory ones aren’t working efficient enough

O2 sensor spacer

Extremely happy with this purchase. CEL not faulted once. Works as advertised.

It works

I installed an aftermarket catalytic converter and the check engine light stayed on with the code of catalyst system efficiency below threshold. I purchased the adapter. Simple installation, and the check engine light and the associated codes are gone.

“Cat-code delete”

Bought a 97 Jeep Wrangler 4.0 recently and the cat was plugged. Removed the cat and replaced with an FX Flowmaster. Engine light has been on since then. Decided to try this little device. Screwed in the O2 sensor, plugged it in, zip tied it up and a few hours later engine code disappeared. Amazing.

Very professional

Ordered this part but unfortunately did not fit my truck. The customer service was excellent in the returning process.

Fast shipping works great great price

Great product

I received my parts in 3 days and on the other side of the country. Awesome product looks beefier than I expected. I haven’t installed them yet as it’s in the negative digits here in Pennsylvania today.

Primera vez que uso este producto.

es la primera vez que uso este producto, y desde que lo instale hace un par de dias,ya no me ha encendido la luz en el tablero. espero y siga asi por mas tiempo.gracias

The problem troubles me for a month was solved! And runs more stalble than before

good stuff man good stuff

good stuff man good stuff

Bought one that looked the same for $20 elsewhere and it didn't work at all. Bought an expensive one here and the light didn't on any more, it work.

The spacer worked exactly as intended. Took care of my unwanted code after an aftermarket downpipe install on my MK6 GTI. Fit was good. Quality was good.

Great timing thank you

Great timing thank you

It Does The Job

This device actually work, it does eliminates the CEL, fits right on, I would recommend you to check if have enough space behind the O2 sensor because it does add over an inch of space

Been working as advertised for one week on one

Been working as advertised for one week on one vehicle and three days on another so far- so good. I think time will be the true test.

Part Review

Received part….so far this has not correct/cleared the code. So, don’t have a honest opinion yet. Hopefully after a few driving cycles it will work.

It is very suitable for my Toyota, the accessories are complete and practical

Works great! The quality of the product is very good, made of stainless steel, highly recommended!

PASSED EMISSIONS!!!

This product is the only thing that helped me over the last 2 years I’ve replaced O2 sensors and converters and the light was still on! Now the light is out and I passed! Highly recommend!

Very very pleased !!!

Great part used for a 2012 mustang with catless mid pipes, did there job even before I got the vehicle tuned. No CEI lights at all about 300 miles of driving. Great substitute for the hard to find nowadays manufactuer specific MIL eliminators.
