Discounted units? Any more info on this? Or can you pick it up without the k&n?
And about the k&n...I thought the conclusion was they were worth 0 power a couple of years ago, right? So is Ford saying we should use the k&n filter in order for the tune to be, for lack of better words, optimum as far as tuning? If you didn't run it...could THAT be a warranty issue?
I know, a lot of questions but I'm just thinking it out as I type.
Any non-oem filter element in the stock airbox is worth zero. Ford includes it to justify more $$.
