O2 Oxygen Sensor 15717 Downstream Upstream Compatible with 1990-2014 Ford F150 F250 F350 Ranger Escape Explorer Lincoln Mazda Mercury Replaces 15716 15718 Set of 4

Well worth the money, the engine light when out, they were easy to install on my Ford, wire length good, functionality, engine performance is better than before.

This is my second time buying this set. They are an easy install that fits correctly. The quality and functionality is obvious as my check engine light was fixed both times. Great value and great quality

Perfect replacement, fixed my issues, clear my check engine light.

Exact match and have had no part failure issues BUT relying on knowing the exact bank location or if it's upstream or downstream based on cord length or sensor appearance is almost impossible so yeah if they arrived with either detailed information or each cord tagged it would dramatically cut the amount of frustration & time when installing

Perfect fit

Product is great, for the price it is very very good, installation takes no more that 5 minutes and very durable I was actually surprised but you get what you pay for recommend.

Caused additional trouble code. I had a LEAN FUEL MIXTURE code (P174?) and figured that replacing the O2 sensors was a good place to start since they were very old. These are supposed to be upstream/downstream compatible but that doesn't seem to be the case in my situation. Car stalls and has no power (undriveable) but ran like a dream before I installed these O2 sensors (trying to get inspection but check engine is on). Now has P1151 lack of (SO241?) switches. Gonna swap these out for OEM which is gonna cost me almost $200 as opposed to 40 but sometimes shortcuts aren't worth it. I hope they'll accept a return because this was $40 down the toilet.

Part was accurate and was at a very affordable price.

👍🏻👍🏻

Although they function I am still getting rich o2 sensor codes from my ecu. Not sure if it is the aftermarket o2 sensors or something else

Good product
