NTK (24355) Air/Fuel Ratio Sensor

Quality product. A tad pricier than others. Don’t buy twice Buy quality

Perfect fit, improved millege right away..(old sensor was busted).Easy to install with the right tools...I sprayed wd40 couple of times 2-3 days before, rented O2 sensor removal tool from Autozone and was done in 10 min.

NTK is the best when it comes to O2 sensors. This is the OEM for my Mazda and it immediately took care of my P0134 check engine light. Easy to install and has everything you need.

Serves its purpose. So far so good. Purchased about six months ago

This sensor worked great in my 2006 2.3L Mazda 3 with 125k miles. It came with some anti-seize already on the threads and was a direct replacement to the existing sensor. It has been 3 weeks with no more CELs.I was a bit paranoid about stripping the threads out of my exhaust manifold. So, to install I soaked the threads of my old sensor with PB Blast for 6 hours, then ran my car around town until it was good and hot. Removal of the old sensor was easy at that point with an O2 Sensor socket.After installation I plotted the old sensor data next to the new, and they were remarkably similar. This gave me an assurance that this would perform as a direct OEM replacement for much less than the direct Mazda part cost.

Very accurate works good

Fits my car and fixed the check engine light

Se instalo y funciono perfectamente

Good price and work for my Mazda 5.
