Why waste your money on something that doesn't help your truck? It can actually do more harm than good. Do a search for A/M intakes and you'll see why.

They do not filter out dirt as good, which can lead to turbo damage. The factory intake also flows enough air to support 500 HP so there is no benefit.

AlienMotorsports,

I agree 100% with npccpartsman & schmidt64, also the OEM Donaldson filter holds over 3Lbs of dirt and if properly changed based on the "filter minder" is good for 60-80K miles between changes.

In addition, several tests on A/M air filters on various websites, the K&N always has one of the worst filtration rates of any of the filters tested and this includes stock factory paper elements.

So since the K&N has a poor filtration track record, the stock OEM Donaldson flow more air than the 6.0 can use until you exceed 500 RWHP, and the OEM Donaldson filter is good for up to 80K miles, why waste your money?

The money spent on an A/M air intake for the 6.0 can be better spent on items that will be beneficial to the 6.0 & Torqushift.

I run the AFE Proguard 7 open element yellow filter kit and have not found any trace of dust or any other particles in my intake boot and throttle body. I purchased a second filter so that I don't have to wait to drive my truck while the filter I'm cleaning dries. I've had it for a year and plan on servicing/cleaning it every 6-9k miles or 6-9 months although it is strongly recommended that it be cleaned every 15k miles or so.

Should I have find a trace of dust, dirt, or any other element in my intake boot or throttle body, it will definitely be coming off.

Oh yeah, I remove the filter and inspect the intake boot every 90 days for good measure.

Don't look for dust in the pipes; examine the leading edges of the impeller vanes on the turbo; of course by the time they show damage it's way too late. I remember a training video; I can't remember if it was from Cummins or Caterpillar; but the long and the short of it is that less than 1/2 a cup of fines will totally dust an engine, turbo damage, cylinder damage; the works. Why would you want to risk that? Unless you're pulling 500+HP and need every ounce of power from the engine it just makes so much more sense to stick with the stock setup.
