It's a cheap intake mod. The stock air filter box is garbage and does not seal well. Instead of dropping $200-$400 or more on an intake (aFe, Ford AIS), a lot of us got a piece of 4" diameter aluminum (or exhaust piping), modified/removed our air box base and dropped in a big ol' air filter (Napa part number 46637) for less than $100.

You can find one here:

The 6637 is the "Big Honkin' Air Filter" on the right side of this pic:

Not enough to worry about. I think the AFE was one of the ones tested on the dyno with the 6637. It was only a couple HP different.

You can go here for all the info. Welcome to Pete's 6637 Intake Cover Web Page

I had a member of FTE *i forget* send me a pc of a 4" 4 long of exhaust pipe.. Really only need 2.5 long. I found my dads 4" up at the local garage. To attach the new filter to the existing intake tube.

Thanks on the Comps.
Got that right.. Plus a set of hood hinges(opening the hood so much).. If it looks like crap when i opened the hood, i get after it and clean it up.. There are a bunch more things i want to get after. Didn't do much last summer. It rained so much.
