Air intakes- which one ?
My 04 PSD is stock except for the Diablo Predator. I just ordered a MBRP cat back system. Should I change the air intake, and if so, which one. I have looked at Airraid,AFE and K&N and am leaning towards the Airraid. My truck is used for light duty,has 7K miles and had been trouble free. All I have done is change oil twice and rotate the tires. I love this beast !

Unless you're going to run over 3K on the tachometer all the time you really won't get any benefit from aftermarket filters. The factory Donaldson unit provides extremely good air flow and the ultimate protection for your unit. I have the Airaid unit and took it off because IMHO it didn't provide adequate filtration for the turbo setup. The only place you really make horsepower with the aftermarket filters is way way up in the powerband. I have the zoodad mod on my truck (opens the airfilter up to all the elements from front) and have had no problems with the factory filter. I usually average about 18mpg running 80 on the highway. You'll get more benefit from Powerservice or Stanadyne than the AM filter. Besides that you can buy lots of BETTER donaldson filters (about 200k miles worth) for what you're gonna spend on that aftermarket setup, provided you don't buy them from the dealer! They're available for about 40 bucks online at one or two places. They just don't have the motorcraft name on them, still Donaldson tho (they make the filter for Ford).

I have run stock, K&N fipk, and the AFE stage II w/ proguard filter. And I personally think the AFE is by far the best w/ noticable gain, especially in the low RPM torque. Although it was rather expensive, I found it hard to justify the almost 2x difference from the K&N, but went for it anyway, and I am not dissapointed.

I actually went with the Airraid and am quite happy with it. It does have a little whistle but itis not bothersome. I immediately felt the difference. I am not as happy with my MBRP cat back system- it may be breathing easier but I have not felt any power gain.......

Stock is best.
Ford is very strict on intake mods.If your turbo or any thing else goes bad on the Intake side you are toast!
I read on another site about a test of all the popular brands of air filters and the Donaldson(maker of the 6.0 filter) was second only to (gulp) AC Delco. I think Proguard was 4th

1 thing to consider is that Ford stuffs a Donaldson filter in there - already a great filter. IMO prolly the best in light duty diesel trucks. Plus I've never seen it where an after-market filter adds HP/TQ on any dyno tests to a Ford 6.0 PSD even though they all advertise they do.
BUT (There is always a but) when coupled with a turbo-back exhaust it sure sounds good!

I will have to retract my comment on the AFE stage 2 setup. Because my check engine light came on after about 20 miles(anyone know of a code reader that will work on the 05 6.0? other than a $300 programmer). Went back to stock no check engine on for 300 miles so far, I am in process of contacting AFE and trying to get my money back.

b_dub, I had the same problem, I don't remember who I talked to at AFE, but they were aware of the check engine light issue. Coincidently, I took my truck to the dealer a few weeks later (stock filter) and they had to replace two of my sensors and some other stuff. Made me wonder? Maybe those sensors being bad caused my check engine light to come on after I installed the filter? I would like to try the filter again, but it was a small pain returning it and getting my money back.

I called AFE first, explained my problem and told the name of the AFE technician to the vendor I purchased the filter from, I only had to pay return shipping, but it took 1 month to get my credit. My suggestion, start with AFE, then the vendor. Good luck.
