O2 Sensor Spacer Adapter Extender

Good product and has been working great. Used to space out downstream O2 since catalytic converter had failed on my Dad's 2005 Altima. Has not thrown a code and passes emissions fine.

Worked as advertised. Got rid of the P0420 code after replacing my header. I'd use this on any car that is having issues with it after removing a precat header

Still not in use but the part looks like real quality.

I put this on my 03 civic because I have aftermarket headers with no cat ..and my cars performance was suffering because of the o2 sensor was reading bad emissions ..so I put this adapter on the o2 sensor cleared the check engine light and started it up and hasn't come back on since .. Made my engine run great again ..good product for the price

choose five star rating cause product saved me time & money, I liked the product due to easy installation, make sure when ordering this product make sure you have enough clearance in compartment might have to order 90 degree angle instead. Recommend for do it yourself mechanics.

Would recommend.

I did research on replacing pre cat on 2002 altima and read I would be needing this adapter. So I ordered it, slapped it in and no error codes. No hassle, shipped fast, got the right part the first time.

97 chevy 350. works. i got this one and the 90 degree version also for the other side. replaced the old sensors with some new ones , no more check engine light
