I want a filter for my truck and i was wondering what yall thought about them. My truck is all stock except for smoke stacks. I dont have a chip, i just want a intake to help the milage a little. Im leaning toward the k&n pod style filter.

If you mean AIR filter, probably the best is the Ford AIS. You can get it for $200 at http://www.powerstrokeshop.com who is also a sponsor of TDS. Much more air, much higher / finer filtration.
You can also make one yourself with the right Baldwin filter and some fittings. Look up the do-it-yourself "DIY intake" or "DIY Tymar" or "Tymar setup" with the SEARCH feature on this site. It'll run you about $50.
After that, you'll have to go with the aFe Stage 2 with the good filter (can't remember the name), and it will run you $400-500. Don't get the cheaper setup of the Stage 2 with the lower quality filter.
You can get the Donaldson filter through Amsoil for less than $40, I've got 2 PVC fittings and the filter and don't have any complaints other than it's a little noisy in the cab, a little noise suppression cloth stuff should take care of that.
Never use a K&N. Bets is either a Tymar or Fords AIS period. All the rest are second and just add bling and lighten your wallet.

Before I came on here and learned of why not to use a K&N filter, I had the K&N FIPK system. The air box that comes with it and the tube that it provides to replace the rubbery flex tube stock garbage are second to none, if you can find one used on ebay, do it then do what I did and get the Napa 6637 Filter like the DIY or the Tymar, that way you get the best of both worlds. My system will outflow the tymar and still won't sandblast the turbo like a K&N

Anyway, I installed the Fram today (I'm no fram fan, haven't used their junk oil filters for years) and can't say I see any more boost or more noise as some people say but I just burned up the hill from my house. Haven't taken it on the hwy yet. Just a quick shakedown run.
Unfortunately Lordco Auto Parts - Home Page autoparts ripped me to the tune of $57cdn for it. Rip off artists. $1.69 for the 4" diameter white plastic pipe piece, $3 for clamp. Just cut the pipe piece to side and chamfered the edges a bit. Was a b*stard to get the pipe into the hard plastic/rubber of the filter. Had to hammer it in with a board on top. Real tight.
Prob my imagination... seemed to spool a tiny bit faster.
Anyone know what the wastegate actuator is set to open at (psi)? From what I've been reading it's adjustable. Which way is more, which way less?
Edit: After a good drive to work and back... the sound under boost isn't any louder than stock. But if you're on it for a while WOT and then snap the throttle pedal closed the turbo stall sound is incredible... it's probably 3 times as loud as OE air box. Sounds like a blow off valve. :-)
