Welcome bitterroot to irv2.
I have installed a CAI, INSTALL ,from Brazels on my 8.1 Chev W-22, to eliminate problems with rain on MAF sensor. It opened up the radiator area and they say will aid the engine and some better milege.
I have added also ULTRAPOWER for more increase in mileage.
Check out info in the Workhorse forum there are some addons that do help, enjoy the forums and do post often.

I have an aFe system. I have been very anal about trying to quantify the benefits.

cost - when the local dodge dealers more than double the cost of paper throwaway airfilters to $55, I started shopping.

washable/reusable seemed the best way to go. I started researching, and everyone agreed, that the stock airbox and tube was restrictive.

so - financially, spending 400ish on a CAI would take about 8 air filters to pay off.

fuel economy - I noticed about a 10% increase with the trailer attached (read from 10 mpg to 11 mpg). So, on my 06 coast to coast trip, I saved 120 bucks. Now down to 6 filter changes. Without the trailer 2-3 Mpg increase seems to be consistant. so , for every tank, I get a little further down the road so saving even at 5 bucks a tank, Every 10 tanks or so, I have bought back another filter.

Power hasn't been notably different, I can pull some hills faster than I used to (and have retro-fitted back to stock for same run to confirm). Its not neck snapping changes, but they are there.

Sound - noise has increase, but thats not a bad thing

Throttle response/turbo spooling- is noticeable.

I have washed my filter 5 times now, I do it more often because it doesn't cost me anything to do so. In reality, I think that it is now paid for after a year and a half after installation.

I have a 2 two stage AFE on my 2002 Dodge and yes they do save you money on filters and increase airflow- it really is all about Fuel/ Air/Exhaust = better performance

There are different issues to this. Without failure, any filter that reduces flow restriction through the same size plumbing must allow larger contaminants through. I choose not to risk my $10,000 diesel engine longevity by out-guessing design engineers.

Ditto Ray! I've always been leary of after market add-ons. Especially on diesel engines, given the high cost of repairing any potential damage.

Although this was done on Duramax air filters, this is the only independent test of aftermarket filter efficency that I'm aware of, and I found it very interesting. They used ISO testing of restriction and measured dust that past through the various filters.

Filter comparison

In a nutshell, it looks like all the aftermarket filters had slightly less restriction than the factory filter when new, but add a few minutes in dust and soon the factory filter was the least restrictive, and the factory filter allowed the least dust to pass through to the engine...
