BOSCH 12014 Premium OE Fitment Oxygen Sensor - Single

Great product and service!

It actually fit, seems not all 18x1.5mm threads are same?

Good quality part

I used this in my 1993 Chevrolet K1500 5.7 liter 350 z71. It has a single o2 sensor on the left exhaust manifold. It was 33 years old (factory original). I know because I've had it since new. I never got a check engine light, but I read that the o2 sensors will get lazy and after 33 years mine was probably bed ridden. I replaced it and unplugged the ECU fuse to reset the ECU. The truck has a little bit better throttle response and better idle when warm. Bosch is the OG o2 sensor maker, so i trust they do it right.

Arrived very quickly,I squirded the o2 sensor with wd40, and did the same a few days later. This done on cold engine,and replacement done on cold engine. Biggest problem was getting the correct o2 wrench size, used the new O2 sensor to measure. Had to remove one vacume hose to get to old sensor, then once I GOT WRENCH ON SENSOR, loosing sensor was no problem, 1/4 turn with wrench nd it came loose easily. New Senor comes with antiseize compound on threads finger tight and 1/2 turn to sung up, replace connector to O2 sensor and vacume line. Ready to go. Great price easy job.

Fat handed the old sensor while doing a tune up and snapped that sucker off. This one fit perfectly and no codes so obviously it also works perfectly. Zero complaints

Seems to be legit OEM O2 sensor. I matched my original sensor. Swapped them out. No issues so far.

Product exceeded anticipated

Works great. Good quality materials. Used in my 86 Corvette. No issues. Recommend.
