Sensor arrived quickly and was well packaged. Fit and functioned as original and fixed my lean codes. Price was much better than local parts place by over half.

Where do I begin?TLDR: DO NOT BUY this for an 08 Ford Escape Hybrid, purchase the original MAF sensorMy vehicle drove me crazy for months with Stop Safely Now errors, shutting off, re-jumping the hybrid battery etc. I had replaced one of the hybrid battery fans, the door actuator, both vehicle air filters, and well the MAF sensor. This MAF sensor. And I was still continuing to get Stop Safely Now dash warnings and Forscan codes.I took it to a mechanic who said I need a new vehicle computer for $1100 because it was broke and wouldn't communicate with the MAF sensor. I thought that was bs, so I didn't go through with it. So I paid to tow it to a hybrid mechanic. Low and behold, they told me the after-marktet MAF sensor was the issue. I was skeptical, but I'll be damned if after putting in a different MAF sensor, my vehicle is back to running like a charm again. I would have never ever figured that out because I thought buying this one, which says it works for my vehicle, is total bs. Don't buy this.

I guess the best thing to know about this sensor is that it works and it wasn't overly priced. Is not the cheapest one by far, In about the middle of the Is prices. My car accepted it as OK, And that's what mattered

Easy to replace on the ford 5.4, make sure to disconnect your negative cable from your battery prior to installation, resets your engine contrôle module.
