Features:

  • It Is Suitable For All Standard Oxygen Sensors - most modern vehicles are equipped with M18x1.5mm threaded oxygen sensors. our product of oxygen sensors' size is M18x1.5mm threads. And you can easily screw your oxygen sensor into the spacer and then the spacer into your exhaust.
  • Avoid Checking Engine Light- oxygen sensor Spacer catalyze the oxygen sensor to discharge the exhaust flow. By separating the sensors, you can try to avoid checking the engine light due to the high flow catalytic converter or the test pipe.
  • Configuration-This exhaust oxygen sensor spacer has a 90 degree section and 3 different adapters. you can adjust the length of the oxygen sensor spacer, which incluing one side of the vent pipe and other side of the oxygen sensor.
  • Design For 90 Degree- with 90 degree compact design and modular fittings, the oxygen spacer will be applied to a limited space. This will avoid damaging your oxygen sensor.
  • Material-made of mild steel and nickel plated on the surface which can avoid cracking and excessive heat expansion. And you can get one set oxygen sensor adapter
As Described

I haven't had time to try this, but shipment was quick and the machining of the parts is professional. Whether this does what I want it to or not will not be because of the quality of the parts. That's why the 5 stars.

Works and fits great on my Evo X for getting rid of CEL engine code!

Came with everything needed for installation and worked great on my 2014 Evo X GSR

High quality, easy install.

Used these on my 2000 VW Passat. they did the trick and seem like they will last as long as the exhaust. Highly recommend.

o2 censer devertor to help pass emmission they work very cool

they work like a 60's style oil fouller you put them in line of your o2 censors and sends the exhaust to a different passage and stops light from coming on thanks again

So far so good.

Well designed. I opted for the 90* bend unit of the 3 that come with. It has a lock nut to position the o2 where you need it. After an ecu reset it’s tricked the computer so far.

They do the job

If you install a high flow cat you need these due to more air/oxygen in the exhaust tubes.The downstream O2 sensor reads more O2 and sends a code.With these extensions it takes the O2 sensor out of the stream and eliminates a code being sent.

Good quality and fits like a glove lol.

Really good quality, easy install and strong design, pretty heavy material. O2 fits perfectly. You get everything shown in pic. Will buy again. Got it when I needed it, took 2 days with prime like usual.

2005 Scion Tc p0420 CEL is gone

I used on my 2005 Scion Tc i had bad cat so i used only one spacer . this works like a pro .. do not waste money on cat just buy this and extend the O2 sensor you will save thousands of dollars Some of you may say you need to put new cat because save the environment how about you start recycling plastic insted of talking about emission control rules ...

This is a good L pipe

This is a good L pipe. It's good for those have older model car that has a check engine light and need to fool the o2 sensors. Solid metal construction. Will buy again.
