Just installed a K&N CAI yesterday so far so good.

I have an existing 5 star tune but I don't think I need to retune it just for the CAI. (Please keep me honest here of course). A review to come (yeah I know it's not a major mod, but I'll still post my thoughts here) after the engine learns it a bit.

Overall though very happy and it looks much better than the stock one IMHO. :)

Happy Thanksgiving to all!

Looks great man. I’m planning on eventually upgrading the CAI & intercooler.

How are you liking the 5star tune? Did you notice a difference? I just ordered mine (arrives tomorrow) and I’m so excited.

Oh brother... On an Ecoboost none the less... Hope you don't take your Expy down many dirt roads... K&n (or any "cold air intake" ) is hell on turbo vanes.

YUP. Makes a nice 'Duster'. Ford diesel guys quit using those back in the late 90 Powerstrokes for that reason. They are used at the track but you don't have all that air borne junk and they change/oil their filters pretty often on the track.
