They made it right

Took a minute with some shipping issues, but they made it right!!!

My 2001 Silverado smoothed out immediately and gained in gas mileage

This thing actually works.

Everybody needs to buy a bunch of these now, while they are still available. Give one to each of your loved ones. If you live in a communist state, like New York, you are going to need it.

No check engine light

Installed, and driving it back and forth to work for a week now and no check engine light yet. Fingers crossed, thanks.

Worked like a champ

I couldn't have gotten the job done without this kit. The 22mm and 7/8 sockets worked perfectly for my hard to reach bank one sensor 1 O2 sensor in my 2018 GMC Sierra 1500 truck. I highly recommend this product.

fit properly seem to be good qualitythis kit worked well for me

this kit worked well for me i used the thread chaser and it worked to clean the threads i liked that there are options as to which socket you can use

Handy tool to have

Great product and price makes it easier to get at the O2 sensors in my bike

works as expected.

having this tool to change my ox sensor made things so much better. i have removed sensors before however it was a pain. this tool made it so much quicker and easier. my only complaint is that the hole where the wrench goes was a little tight. Had to deburr the inside a little.

Peace of Mind for Privacy

As someone who prioritizes privacy, the Vanishing Plate provides reassurance while driving.

O2 Adapter Success

Works perfectly—no CEL code and has been flawless since installation!

Testing the Bypass Adapter

Installed the parts today and hoping it works. Much cheaper than replacing the full Y-pipe with new cats. Fingers crossed—seems to have worked well for others!

Great Fix, Works Perfectly!

After a few adjustments and some wiring, it works perfectly. Thanks for the fix!

It works!

Solved my CEL, due to my tune, and works as designed and claimed! Thank you!

Check Engine Light Solved

Resolved my check engine light problem quickly; the part arrived perfectly packaged and in excellent condition.

Must have

It’s a great design very durable tool and fits perfectly on the o2 sensor makes the job easier and faster

Very useful

I had to change a O2 sensor. with this set I did it in 30 minutes. Perfect!

The Vanish Plate has been an indispensable addition to my vehicle ever since I started using it.

Easy installation and compatible with second-gen 4x4 S10. After 500 miles, the CEL hasn’t come back.

GREAT product, saves MONEY !!!

Worked on my HHR!!

Saved me money and time!

This part saved me so much! The upstream O2 was not working properly but I did not have the tools or money to get it replaced. I was able to use this on the down stream O2 sensor, that's easy to reach, and get my car smog checked and pass! Thank you so much to all those involved making this part and saving my low-income self from losing lots of money!
