its a PZEV and has a lifetime filter. i removed it and installed a cone filter but recently had to put it back in so ford would warranty the clogged mani/cat it had last week.. and i do the fuel filter every 15k or so miles sometimes more often, and i had a buddy help me 2 summers ago instal e3's what a HUGE mistake that was.. 56 miles from town had the number 2 plug back completely out just so happened to be one of the 2 plugs my buddy installed.. all bad not knowing at that time i drove it on 3 cylinders all the way to my local ford dealer 1200 later got it back fine they said nothing was damaged so about 30k ago it got brand new oem plugs the ford installed haven't changed them since,I've heard a tune gets rid of the rough idle but its alot worse then it has ever been?
