Intake recommendations?
I'm debating on getting a K&N Fuel injection performance intake for my 5.4 or would I be better off with the gotts mod and K&N air filter or just another intake brand all together?

Yes, and it still gets COLD air from the fenderwell, not HOT air from under the hood. A DRY air filter won't foul the MAF with oil and it WILL filter better.
The only reason to get a K&N is to make noise and look cool.

Then get an intake that still gets external air and uses a dry filter. If this is a 04+ you will probably need a programmer and custom tunes to avoid running lean.

Yes, because the MAF is no longer in the same position. This may need to be compensated for with a tune. This is especially a problem with the 5.4 3 valve.

I've been running a Roush intake on my '07 5.4 for about 3 years now just fine. I've got the Roush exhaust on it as well. (local dealer was selling parts at cost) The Roush intake looks exactly like an AirAid intake to me. anyway, Ford doesn't void the warrenty on the Roush set up because the increased air flow is still inside the stock EFI system's ability to adjust. I tow with my setup. couple of more MPH and more throttle response without a tune. Deffinately worth it for me since i obtained parts at cost and installed myself. the only drag was walking away from the Roush supercharger he wanted to sell at cost as well.

The only way you'll know yer 'fine', on your specific truck, is via direct measurment. Period.

On Fords, the mass air sensor is used to determine fueling, its also used to determine load. Spark timing is calculated based on load. If your mass air transfer function is shifted lean, your car will be too lean and it will have too much timing, which is a very bad combination.

Intakes that do not require a tune are often just as restrictive as stock and do not result in large power gains.

It's not like the 2-valve & 4-valve modular motors, the 3V's have a different MAS system and it's far more unforgiving of changes made to the air intake tract. What Bartak1 very kindly responded with is accurate info for the 1997-2003 trucks, but not for the 2004 & up 5.4 3V motors.
We've gone over all of this many times before, so you can use the SEARCH feature here to retrieve & read any of our hundreds of previous posts on this exact topic.
By the way - THANK YOU for asking about this before doing it - so many people just accept what the various manufacturers claim and slap on intake kits and then have problems, or in some cases don't get any warning lights on the dash - we've seen 19:1 lean not throw a code on some of the 5.4 3Vs during a full-throttle dyno pull, and that is scary.

YES! But not because it's getting more air. Since the OEM intake isn't limiting air flow, you won't get any more air with a larger diameter intake tube. What
happens is the air velocity goes down, causing the MAF sensor air flow measurement to be off. Do your wallet, and truck a big favor and stick with the OEM CAI.

I run an Airaid, not as pretty as some of the others on the market but it's been fine for me. I clean the MAF a few weeks after as well. I go light on the re-oil.
Gotta agree with Camopaint0707, the stock intake is just an ugly massive piece-o-plastic mess in there.
