Solved the Problem
Cheaper versions did not satisfy my onboard computer of my 04 Jaguar XJR. This MAF Sensor turned of the Check Engine Light.

Knock off but working
This is not a genuine Delphi product. Someone is using the name but arrived in a box that is not a licensed Delphi box. Seems to be working okay so far

Did not work on 2008 Jaguar XKR
Okay, I should have known better. Looked the same as OEM however, inspection showed that it was badly made. I went ahead and installed on circuit B which was a royal pain and within 10 miles I had lean bank 1 and 2 codes.Ended up buying the more expensive Denso and zero issues.As noted by others, this has a label that states you cannot return once opened, not a good sign at all.Mine is now in the trash can.

Received opened! Clearly says "No Return if Opened"
Just opened the package, took the MAF out of the box. The MAF is in a clear plastic clam shell with a sticker that ssys, "No Return if Opened." It was already opened!

Didn't work. Ran worse at idle than the original one.
Used on a 2002 Jaguar XK8 and it wouldn't idle without loping. Got one from the junkyard and car runs fine now. Waste of money. Car only has 53,000 miles on it.

Buyer Beware !!
Did not work at 'll, my mechanic replaced it with a real OEM part even though this one is advertised as OEM. Buyer beware !!
