I have a roush cold air. It won't affect your warranty. In fact I may sell mine soon to get the better cold air setup

 

Also if you want to just here the intake, ford stuck a pipe on the intake that runs to the firewall. It's only purpose is to give you sound to your cab area. The tube that runs into the fire wall, pull it off and pull the sponge type material out. Then connect the pipe back on there.

 

What do you mean by "better cold air setup"?
All CAI's are about the same, minimal difference.

 

Because there is a reason that the roush cold air does not require a tune. the kit only comes with the air box, filter and the piece that connects the mass air flow sensor. Does not come with the rest of the piping.
This is my intake right now.

This is what I'm looking for



Plus that intake tube ford put on just to give sound to the cabin is annoying now and I lost the baffle for it.

 

^^Interesting....^^ The stock inlet tube looks big enough for good airflow. =-)

My Araid CAI came with the inlet tubing, airfilter and the heat shield. Airaid also does NOT require a tune, however the performance was minimal without it. Once I uploaded my custom tunes, it was night and day! =-)

 

The inlet tube is big but the flow is different compared to the other Cai I posted. also it deletes the tube that runs to the firewall which is what i would like to do. It's like the old saying is, don't judge a book by its cover
