Don't do it. The K&N flows better because is less restrictive -- and the trade-off is it does not filter as well. The stock filter from Donaldson stops 99.99% down to 1 micron. Run in the same environment, if the stock filter let through .1 gram, here is what gets through filters at other efficiency levels.
<LI> 95% efficiency -- 50 grams
<LI>99.0% efficiency -- 10 grams
<LI> 99.9% efficiency -- 1 gram
<LI> 99.99% efficiency -- .1 gram
K&N is around a 96% filter. You'd be letting a lot more junk through to your engine and putting your warranty at risk, as other posters mentioned.

Guys, did I miss something? I've got an 03 6.0 and about two weeks ago I replied to some guys post about the air filter.
Unless I'm really losing it, my manual said to inspect regularly but the replacement interval was at 60K.
I've got 42K on mine now...the gauge hasn't moved at all. I've already bought my replacement filter (a Motorcraft) and am just waiting for the milage to roll up.

The First printing of the Diesel Supplement manaual for the 2003 said to change the air filter at 60k on page 52 and to change the air filter based on the filter restriction gauge at the top of page 7.
ALL other printings of the Diesel Supplement manual to date (including the Second printing of the 2003 manual) say to Only change the air filter when the filter restriction gauge indicates.
You can change at 60k if you want, but the filter minder is accurate, is the way to determine air filter change interval per FMC and is IMO the best indicator of when to change the air filter.
Hope this helps

Thanks blackhat...I was concerned the senior moment thing was happening again!
I'm comfortable using the filter minder. Even if someone has reset it, it should read the blockage and display.
I just wasn't sure why some of the guys were planning their change so much earlier based on the info I have.

msgtg,
Nope no senior moment, just changes to clear up conflicting information during reprint.
Some guys don't feel comfortable using a filter minder as it is foreign to there way of thinking and so they change the air filter based on mileage, engine hours or looks. If the air filter is changed more often than the filter minder indicates, only negative effect is litening the wallet faster.

Pardon the dumb Q, but does the truck need to be running in order for the filter minder to work properly. Mine hasn't moved either in 25k miles .. light duty .. no real dust/dirt .. getting 16.5 mpg mix city/highway use ... no tune .. I'm not comfy either with filter minder ... also I did the zoodad mod to get increased airflow .. .

post-man,
No the engine does not have to be running for the filter minder to register properly. 25K miles is not very many miles on the Donaldson Powercore filter, i have gone 40K miles with very little movement, and 80K is obtainable depending on how dusty the conditions are you drive in. The filter minder does work, but they don't move alot until the final stages of the filters useful life span and this is normal. Filter minders have been used for years on heavy trucks and off road equipment with great success.

I put an Airaid filter in my stock housing. It was cheaper than the stock, $58, and flows alot more air. I have K&N filters in my other vehicles but they wanted to much for the 6.0 filter. The Airaid is washable and will probably be the last filter you buy. Don

In addition if you have turbo problems FMC is known to take issue with aftermarket air filters and not warranty the failure.
Good luck
