Look at the stock intake and you will find it is already a cold air intake. Air is drawn from the outside of the vehicle through the fender well. There is a way to modify the stock air box that reduces restriction in the system. Search Gotts mod 09-10 to find the "how to".
Aftermarket intakes typically need custom tuning to properly compensate for the changed location of the MAF. Oiled filters that come with many aftermarket intakes also provide less filtration efficiency.

I thought about getting an exhaust for my 2009 xlt and installing a CAI right after that. I was warned by several people not too. They said I will get moisture inside my engine causing failure.

Gotts mod. $10-12, all the performance benefits; spend your $$ on a Gryphon, e-fans, etc.

Good luck!

No. I just installed a K&N series 63. No problems. No codes, no pinging or death rattle, and only a bit more noise above 3000 rpms.

I have a 2002 F150 with a 5.4. When I talked to the parts guy about a K&N cold air intake he suggested not. He said the 5.4 will run too hot and cause spark plugs to burn up and also make them hard to change. What have you guys heard?

What he is trying to refer to is running lean. The 2v 5.4L don't have as large of problems with intakes and running lean, but any time the MAF is moved tuning corrections are needed for best results. The main concern with an oiled filter is filtration efficiency and fouling the MAF.

If you are going to get an intake, get a S&B. They out perform any other competior intake
