I first tried the K&N panel drop in years ago, before anyone knew they filtered poorly. It helped spool-up and mpg. After I hit 100k I put in a DP Tuner chip and 4" exhaust and ran that awhile.
I had debated between the Ford AIS and the S&B for a long time. Both were purported to flow well and filter great. They were both $200 then. I got the AIS. Big mistake. I do go offroad some, but mostly highway driving. The Donely AIS filter should be good for 50-60k miles. It's huge and traps 5x more dirt than stock. I did the Zoodad (holes drilled in front air dam). My first filter plugged around 25k on it. I didn't notice for a long time because I did not expect it. I noticed lower mpg, more oil leakage, then harder starting and more soot. I finally figured it out. It had a lot of dust in it. New filter. The next only went for 15k w/ NO OFFROADING. No gravel, nothing. Clean, highway driving. The one lasted only 15k before I had intolerable EGT's while pulling. I had to rig a cheap filter on from Autozone while on the highway in WY. Got me home w/ 250 deg lower EGT.
Now. I had to get rid of el-cheapo. I finally ponied up for the S&B oiled. The filters cost the same, but dry is disposable only, so I got oiled. It is great. EGT's stayed low, normal, I mean. I can hear all the flow. I could hear the rigged filter more, but it had NO box at all, only filter on intake hose. I covered the bottom hole. It seemed to me that would only expose it to water, mud, and road dirt from under the fender well. I think the snout and hole facing the fender are enough. They have 8 layers (or is it 7?) Either way, a lot. They are the ONLY company that backs up their system w/ filtration and flow data. I like proof in a product.
I'm not sure why any of these are called "cold air intakes" since they still draw from under the hood.
I hope to add a snorkel someday. The S&B is the only one that is almost stock in configuration and would allow it. It looks great. I did get the pre-filter sock to keep big things out of the mesh, as well.
I love it. Get it!
