    I have a 2003 F250 super duty with a 6.0 power stroke and I wanted to know if anyone out there has put a K&N air intake on there 03' 6.0 and how long has it been on there(miles and time)? How well did it work? Any increase in fuel mpg's? Any more power?were there/ are there any ill affect ? Thanks

    I have read lately that many are moving away from the oiled type filters.... I Never really saw much difference in performance and I have tried both the replacement intakes and the drops in type...I have an AMsoil Nano filter on order......supposedly more air flow.......

    I've heard the K&N intakes allow a lot of junk into the engine. Injen has a diesel intake out there with an amsoil filter element. I thinks its what dmontgomery might be talking about.

    Any filter out there that flows more means it has larger openings, which in turn means more crap. K&N uses oil to help catch this crap, but it still allows it through.

    The only exception to this is the new synthetic media out there.

    Stay away from K&N for diesel applications. They don't like the turbo. The turbo sucks to much through the filter, and the K&N just doesn't work well with them. Go with a AFE stage 2 or the like. Many guys run that and love it!

    I've used KN on my V8 explorer, it didn't do much for me except give a nice sound at high RPM. I haven't put one on my truck yet since I don't spend like spending the money on something that wont do much for me

    If you read the Ford forums, there is no need for an aftermarket intake unless you are going over 500 HP.

    That, and an independent study showed K&N as the worst filter out there for actual filtration.

    Mark is 100% right, the same thing goes for the D-Max.

    I agree to some point, but an intake will drop you're EGTs, and yes stay way from the K&N

    Not nearly as much as an exhaust will.

    The zoodad mod that everyone wants to do on the 6.0hNo does absolutely zip, zero, nada to reduce intake air temps.

    Completely agree with you on that one

    Unless you have an Early 99 Powerstroke. That intake from the factory sucked, and would allow dirt to get past the filter if you didn't put the filter back in EXACTLY like you were supposed to. Or for about $40 you can build your own 7.3 intake and be money ahead and ahead in performance....:D
