AIS filter questions.

I just installed one of the Ford AIS air filters on my truck. I was wondering what I should expect other then a filter with more surface area. Will I see any better performance? Will I see any better milage? Thanks.

P.S. If anyone is wondering this air filter looks to be a lot better then the stock one and it is very easy to install (about 30 minutes or less)

Would just drilling three or four 1" holes do the trick? Didn't want to cut one big hole.

Funny, I was going to do the same thing but after cutting 3-4 1" holes, I just decided to open it up with one long retangle opening and call it good. I found a piece of gutter screen - the screen you use to keep leaves out of your roof gutters - at Home Depot and it had a large diamond grille and a fine screen on the back. I cut a piece to fit over the opening to keep bugs, small animals, screwdrivers, and import cars from getting sucked up into the air filter. /ubbthreads/images/graemlins/smile.gif

With the AIS and Zoodad, I noticed a slight decrease in EGT's but more importantly, I wanted to protect the turbo from getting trashed since I drive a lot of gravel mountain roads in the summer.
