Hey, even if you order from Fleetfilter, their shipping is typically only about 2 days, 3 days max, and you can sometimes save as much as $20 by ordering from them instead of getting it at your local NAPA store. Also, if you order two filters from Fleetfilter, the S&H doesn't change, so you end up getting a better price/filter, which is the way I always order mine.

That's the way we've all been treated when we first came on board here in FTE, and we like to welcome and care for new family members as they (like you) show up.
That's why I just re-installed my stock box. Was tired of the sucking sound. Nice and quiet now and no change in performance.
I'm going to pick up an AIS soon though.
The stock box can leak like a banshee though. I personally like the sounds, but to each his own. I recommend you get that stock box outta there sooner and not later though. We just worked on a truck with a really dusty intake because of that chitty box...
EDIT: With no tunes, you probably won't notice a difference, but with the 10psi increase in boost over stock, I know that box is a serious restriction.
I don't know, but I'm sure it will cause some extra black smoke, which = power loss. I tossed mine in the nearest dumpster when I put on the 6637. You'd have to do back-to-back dyno runs to find out. It would be interesting to see. I'd like to see vacuum numbers in the intake as well.
However, either way, the stock box is trash -- it needs to go. Anything but a K&N...
1. Remove stock air filter box. Unsnap, unscrew...done.
2. Connect 6637 (or similar) filter to intake hose.
a. Use a 4"x4" exhaust pipe (you can typically get it free at a muffler shop). PVC is okay too. You just need a way to connect the filter to the hose. Don't make it more complicated than what it is.
b. Attach filter to exhaust pipe using 4" clamp.
It's a very easy and economical intake system.
I would consider the AIS if you frequent dusty conditions.
I would consider S&B if you want a washable filter to save on filter costs (some people drive a lot of miles). But I don't mind paying <$30 per year for a new 6637 type filter. I don't like worrying about proper oiling of a S&B type filter.
The 6637 is difficult to beat in terms of both performance, efficiency, and cost. Even when cost is not an issue, I still chose 6637.
