Air Filter

Did this mod on my 4.6 and there is indeed a noticeable difference (positive). Didn't have to snip anything; held in place with clips. Took less than 30sec to do.

Sweet Now proceeding outside to try this on my 4.6!

So, on the 4.6, are we talking about the approximately 1/2 inch thick plastic-enclosed foam filter that is housed in the top piece that seats onto the bottom portion of the housing? I was able to remove this foam filter, although the little plastic clips appear to have cracked away from the top portion of the filter housing. I imagine that it can be put back in and held in place by the tight fit.

Yes that's the one. Two foam layers and a carbon mesh in the middle.

OK, that filter sure doesn't seem like it would impede air flow very much, but I do believe the car has a bit more grunt when you hit the gas!

I also noticed there is some sort of a round flip cap down in the bottom of the lower portion of the housing. The cap seems to be held in the closed position by a magnet. The cap covers a round opening. Does anybody know if that thing flips open when you hit the gas pedal?

^ Indeed it does. It works in the higher RPM range. It is held in by one screw if you wish to remove it and have more air all the time. Fair warning: it does give a little better performance but my MPG suffered pretty badly, so I replaced it lol
