Great filter

This filter should be a factory install on all diesel rigs. I have seen a slight fuel mileage increase and reponse, but I bought this mainly for the reusability. Why throw away money with paper filters right?

so far, so good! mostly highway and some dusty off road trails since the install. filter shows light dust and road grime on outside of element but inside still clean. got into the habit of checking my k&n oiled drop in filter before and after off road events and oil changes. the pro dry filter gives me better peace of mind as filtration goes. no more oiling and possible fouling of maf sensors. a better filter indeed.

Great addition

Installed the filter in my 11 Ram 2500 diesel, noticed an increase in fuel mileage, hand calculated to be almost 1.5 mpg increase, also noticed a difference in the throttle response. I would recommend this product to anyone looking for a mileage boost without the cost of a CAI.

So far so good. Haven't had it long enough to see if it's going to increase my mileage much. However, at this point it seems I've picked up about 1mpg and that's averaging less than 30 mph and with lots of warmup time here. It's cold in Idaho right now. Happy.

Excellant for the money. It is easy to install and helps the engine breath. I took of my K&N Oiled filter at my Dodge dealers request. I notice the engine sounds better and I believe I'm getting 1 MPG more. That isn't much but everything helps.

great performance without changing air intake

This is a great upgrade with little risk of dealer trying to void warranty. Looks good and seems to filter well.
