Nothing noticeable with the aFe Pro Dry S air filter (cold air intake is different product, we're talking about filters here). There might be a smidge better fuel mileage, but there are so many factors to fuel mileage that it might not be the filter. Nothing got worse.
Last two tanks averaged 28 MPG and 32 MPG, respectively, representing 1200 miles of travel round trip with 90% highway and 10% gravel/dirt roads. Heavily loaded with gear and a full 16 cubic foot roof box.
I am, however, having an issue getting it to seal to the top of the air box (clean side), so it is letting fine dust through. The filter media is fine (nothing got through that), but that top seal just doesn't sit well enough to withstand the suction created by the turbo at full spool.
I'm working with aFe to see if they have any tips or if this is a defective filter. It's also possible that my filter housing is somehow uneven enough to cause the trouble. Still troubleshooting.
Oh, and I also just called to open a case with Chrysler about the defective OEM filter. They referred me to the dealer to diagnose and replace (which I'll do later today), but now it's on record with the VIN. If more people with do this, we'd get a TSB and it would be a lot easier to get this issue resolved permanently without resorting to aftermarket parts.
I've attached some pictures. First is the top of the air box (clean side) showing what got past the filter. The next three are of the clean side of the aFe Pro Dry S and the dust that made it around that top seal. The last is of the dirty side of the intake so you have an idea of what *didn't* get past the filter.
