This a Lightning MAF?
 

I have a mass air meter for my car but I dont really kmow if it is 90mm or not. I got it from my work for real cheap and I can take it back if its the wrong size. I measured it and its 90mm on one end and 85mm on the other. The part numbers on the MAF are: F81F-12B579-BA and AFH80-06

Is this the 90mm Lightning MAF that I have?

i think that its an 80mm since there is an 80 in the part number instead of a 90..dont quote me but i believe that randy told us that the size is specified somewhere in the part number

Im going to move this so Randy will answer it. He'll know better then anyone else.

thats IS NOT a LMAF a 90MM LMAF is part # 1L3Z-12B579-AA and we have them in stock if you need 1 but why do you think you need a larger MAF?

Thanks for letting me know. The computer at work said that this MAF was for an 03 Lightning, but the computers there dont work well with anything other than factory replacement junk parts.

My tuner said I need the 90mm MAF with my blower setup. He said all the other ones that he has tried to tune with the stock MAF pegged out and they always end up having to put a Mafia on it. I may as well put one on since there are more upgrades coming in January.

ok but you do know your MAF is 85mm and going to a 90mm will require some modding of the air inlet track?

Well, I know I need to get a bigger MAF adapter (the one that bolts to the inner fenderwell), but Delk said they could modify it to fit. I may just order one incase. Other than that the filter and flex hose should fit right on it.
