MOSTPLUS O2 Male Oxygen Sensor Up Down Stream Compatible with Ford F-150 F-250 5.4L (Set of 4) (4)

The box was just opened and I was ready to install when I got around to it. I found only 2 in my box, and both had the same wire connector. There are supposed to be four. I have no idea if the four are front or rear I have not checked, but I think the four do not share Stay away from the area. It would have been nice if I had replied to other customers.

Taking this 02 sensor to my mechanic was a good idea. In one look, he told me that I was A local auto repair shop Here are four different part numbers shown in the parts store. There is no difference between these four. It is strange that shops show four different parts numbers when they can all be the same. As a result, I now have to stay with them due to my delay in returning.

There are three downstream sensors and only two of them have the right connector to be used upstream.

They were purchased so I could do them My driveway only had ramps so I couldn't get the right angle because of the limited ground clearance. I borrowed the special tool, but because of the ramps, I couldn't get the right angle. Taking them to my mechanic was a good idea. A problem with the car developed after installing the unit. To replace the Motorcraft sensors again, I had to purchase them and have them changed by the mechanic. It is good that my mechanic is not a rip off, or I would have had It took too long for the sensor wires to reach the sensors. Using aftermarket parts for this application won't make any sense if you're cutting corners. Those were for a 2010 V6 I have a Mustang 6.

Since all sensors can be replaced at once, I thought it would be easier to avoid twice as much It seemed like a good idea at the time. There was a failure in the after-convertor sensors. They are on opposite ends. This is amazing. So I installed the factory sensors again and the problem is I have now cleared all codes, and don't have any more O2 That question made me wonder what went wrong. There is a problem with both rear sensors' heating elements. There is no doubt that the cats were overheating that caused the issue to occur. There are still two front-mounted sensors in place and they are working fine. The cheaper price may not be as good as it seems. It appears that the internal components of cats cannot handle temperatures of 2000 degrees Fahrenheit. Despite the negatives, this is a great purchase. While the labor on all vehicles is different, and therefore, the cost of replacement differs unless you do it yourself, which is sometimes a difficult task.

The ties worked great, but be sure to use a tie strap to tie the extra length so they don't melt on the exhaust.

It looks fine, but once it was installed, we had a rich condition in the motor that we weren't able to fix. I did not think they worked well with the Ford F150 with the 4 cylinder. The motor is 6 L.
I am unable to exchange or You are right, it is a simpler and cheaper option than buying a more expensive item. In my case, I took the truck to three different mechanics and finally to My oxygen sensors are bad, according to the person who told me.
