Howdy from the westcoast;
I buy my filter's FL820S by the half flat which is 6 filter from our local Ford dealer.Got a good deal,I paid $5.88 ea. they are normally $11.55 ea. if you buy one. Maybe you should try some local dealer's out your way and get the same deal.Your prices might even be better than our's after all your out east eh!
The motorcraft filter is made by purolator but it is far superior that the filter that is marked with the purolator logo. The FL820S has more filter paper in it and also has a better pressure release valve. Check it out for yourself. They look the same from the outside but look on the inside and you'll see the difference.
