first of all, i'll say it again Wix over fram....
But,
I too am in the parts business for 15+ years, and have a commercial customer who has a collection of almost every filter cut open for inspection. (his preference is K&N but customers wont pay for it)
Fram does make a decent filter, the filter element in a tough gard filter is quality, plus MANY race cars still run the HP filter series from FRAM. Fram is a retail filter line, who puts A LOT of money into advertising....
would you rather have a filter that puts A LOT of money into R&D?? (WIX!)
and Computerguy..... you might start looking at the side of some of those wix filter boxes, some of their filters are made in mexico now
and for the record, FORD filters are made by PUROLATOR.....(I'll be sticking to WIX)
