Probably depends on the filter. I had no difference with my afe. A performance guy I know did a bench flow and none surpassed the oem, and one brand name did worse.

What dP was the test performed at?

With stock mapping the difference between stock/high flow filters is minimal. With a decent tuned map it is able to utilize the extra airflow.

I am not sure what that is, but Conrad of Wagner Tuning performed the tests.

As I said before, the limiting factor is the size the of MAF housing, that's the restriction. If you build enough power you will need to enlarge it. I did but at ~700 crank hp is not something I expect the ecoboost to have to worry about.

So the general consensus is that I should not get an intake. Take that money and use toward a charge air pipe or a tuner?

I'm still leary of getting either of those with as much warranty as I have, as new as the truck is now. Still seems that an intake would be the first step of doing engine mods, and easily removable when I go back to the dealer for service, maintenance, etc.

If you are serious about getting more our of your truck while maintaining the factory warranty then there are really only two things you can change and not void it.

1. Exhaust after the cats. There really isn't much to be gained here, although it is debated. The best I've heard from a reliable source that I trust was 6HP gain, and that was on a tuned truck.

2. Run premium gas. These trucks have very smart computers and do adjust for higher octane fuel unlike those of yesteryear. Some people can't feel the difference, but I did. My brother said he noticed it too only his ecoboost and now he only runs premium. When I was preparing to tune my truck I switched to premium a few tanks before the tune and I felt the difference within 10 miles, and I wasn't expecting any difference. Also, this is the easiest and cheapest mod to undo if you don't notice a difference.

This is my advice as you seem very worried about your warranty. Take it or leave it. I won't be offended.

Since they can void your warranty for the intake, and since there is no benefit to an intake, I'm not sure what your issue is. But this indicates almost any mod can be used as an excuse to void your warranty.

^ It may be worth noting as it is stated that 'warranty may be denied if damage was done RESULTING from the modification'. Per 'Magnusson warranty act'.
