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.

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...

Mini Catalizador O2 Sensor Spacer CEL FIX P0420/P0042/P0430 Code Universal (90 Degree)

I bought this with very little faith it worked but I will definitely admit I was very wrong. I installed it on my 1999 Toyota Avalon and I didn't clear the CEL just to see if the Catalizador would allow the catalyst test to pass. And it did. A couple weeks ago now and so far no light. I had a bit of an issue with installation but it was a wire length issue more than anything. The 90° fit perfectly but the spacing was an issue due to the short downstream O2 sensor wires. I had to do some adapting to get everything to fit in the factory spot. It works perfectly so far. No complaints about fit or function. It does what it says it does. I just hope it lasts a long time. I will be buying again for sure. Great product!

Mini fix for a big problem

Well I bought two 90* and two straight Mini Catalizadors, a straight on drivers side and a 90* on passenger side. and yes they fixed my P0420/P0430 codes. But then I got a P0137 so even though I had another 90* I ordered 4-45*s and put a 45* in place of the straight, After 50 miles no codes. Excellent!

Cleared to get tested

Even after putting in a catalytic converter, I couldn't get my engine light to go away for a catalytic converter efficiency, and this fixed it

Worked…but

Even with 90 degree catalizador I had to do a little prying and bending of the down pipe bottom mount tabs. Nothing major. Left down pipe in place and just used a pry bar to get a little extra room to screw in catalizador. It got rid of the P0420 code, cat efficiency, just like it says. But…..now there’s a new code, P0421, takes two long to heat up. I’m thinking if I used the straight catalizador it would heat up faster and not throw the new code. But my hole for the cat is in a place that would than bring the transmission case into play. The O2 sensor won’t go in because it sticks out too far and hits the trans case. Overall I think this helps even out short and long term fuel trim and downstream O2 sensor readings for the downstream O2 sensor once it heats up and engine is running at constant rpm’s. When it’s accelerating or you’re on and off the gas, stop and go traffic, sensor readings are all over the place and eventually engine will throw O2 sensor inconsistency readings error. So if not too long to heat up engine code eventually inconsistency readings engine code. So still thinking over what solution for none mini main cat replacement issue with P0420 cat efficiency error code. But the device did what it said it would do, no more P0420.

Cleared up my O2 sensor issue

No more check engine light from the O2 sensor

Very good

It works very well and is very good and very good quality

The product speaks for itself, cleared that ridiculous check engine light - thank God!

Quality part !

I have it installed for roughly a week now and it has worked flawlessly.

CONVERTOR LOW EFFICIENCY

WORKED AS ADVERTIZED NO MORE CODES GOOD PRODUCT

Ordered again, very happy

Bought two of these a few months ago for my mustang and work great, was quite surprised. Recently bought a second pair for a friend’s truck and noticed a notable power gain with more exhaust flow. Very happy, will buy from them again.

Worked as advertised

Purchased the mini Catalizador for my 2007 Toyota FJ Cruiser. Replaced the cat and the p0430 came back. So bought this and have been running it for 15 days with no codes. Works as advertised

Mini Catalizodor

These were the best things I have ever bought, it cleared my P-Codes. No more engine light for O2 sensors. I highly recommend them.

A review like no other

I purchased this for my car that was backed into last week by a 16 yo uninsured driver. She had cameras and sensors so she didn't use her eyes. I didn't even get to use this product because it was delivered a few days before my car was totaled. It was delivered in record time and I will hold onto it for future use if it can be used for a different car. Thank you for your product and great service!

Good

The product it’s coming fast best product I recommend thanks master
