Well got bored today and installed a S&B CAI on our 2007 F150 FX4. Very nice piece.

Before:

Intake piece through fender size comparison:



Found this when the intake was taken off. I guess we had visitors:



Install began:



Poop fell out of the stock intake:



Installed:

A shot outside:

 

Did you get custom tunes for that specific intake? If not, you are going to run too lean.

 

Looks great! Nice, clean looking CAI. I may have to look into one of those for my '05.

Meh, I wouldn't worry too much about the running lean thing. If it is, is sooo slight that it won't matter. I don't think an otherwise stock engine is capable of breathing that much more air enough to hurt itself. I ran a very similar K&N CAI on my previous '04 5.4 3v for over 8 years and 150K miles. People always warned me that it was making it lean and killing my engine. Blah-blah-blah.
Guess I didn't listen. I also ran a Superchips Flashpaq with a canned performance tune along with it.
My engine ran strong and purred like a kitten until the little black gal pulled out in front of me and ended that truck.

 

Picture #9 is loading a MPT Performance custom tune for this plus our other mods.

 

something like this my be somewhere down the line for me. How is the improvement over stock?

 

Don't be so quick to say that - the 5.4 3 valve has MAF transfer issues, hence the need for a custom tune.

To the OP: Just making sure your tunes account for all your mods.

 

Oh, I wasn't quick to say that. It was an 8 year/154K mile study. LOL

It passed

 

Thanks for looking out. We had decided to get a tune and wanted to make sure we added the things that needed for tunes. So that is why we added the CAI at this time. Really happy with our dealings with MPT Tuning.
