Fit my 2013 Explorer. Didn't fix our issue, but didn't cause any new problems either.

Exactly as described. Works great

Just installed and it works as described. Smoothed my rough idle and met the expected readings

Ordered this twice and neither measured temperature properly, reads way high. The mass flow reads correct but when the engine control module calculates the air temperature correction for the true mass air flow it gets a much lower result and sends a high EGR flow code etc. 2017 Ford F250 6.7 power stroke. Bought Ford part and ok.

Junk. Never buy a Chinese knock off sensor for a Ford vehicle. This gives bad signals and won’t let the engine idle properly. You’re better off going to a junk yard and pulling a replacement part off a junk vehicle like an old Mustang.
