Sorry I think I was sleeping but...
What is a #10 envelope?
I too would like to get a f150online decal.

 

I saw your mods list paul.......How does the airaid perform on your truck...Sharper sound? Better throttle response? was in worth the 200+........Just wondering....I think im gonna try the little K&N "poor man's air box" trick for now...Just wondering....maybe someday

 

Response is much better mpg up just a little.
I bought mine used so it was less than 200, I would
do the AF1 if I had too give full price (still may change to it).

 

If you decide to change to it you've got a buyer for the airaid......

 

OK I'll keep you in mind
