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.

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.
