FWIW, add another data point to a K&N or oiled filter user who's never had any issues. I've run them in every vehicle I've owned since 1993 with no problems what so ever. None in the "out of the box" state and none after reoiling. Personally, I think the whole oiled filter concern has been blown way out of proportion, but we all need to make our own choices.

There was a comment about Ford designs using the paper filter. Think about it from this perspective. In product design, manufacturers tend to stay with existing components where ever possible, to keep costs down. Changing a filter design, by going to the oiled filter requires substantial design validation and performance verification testing. This costs money, manufacturer's are very choosy about where they will and wont spend money during the design phases of new vehicles. (FWIW, I used to work for a number of automotive OEM suppliers and have been involved in this sort of thing)

I agree that OEMs will typically stay on the safe side and continue to use what's tried and proven. Concerning air filters, I believe Ford would also err on the side of simplicity. Since air filters are something the average Joe can service, adding the complexity of oiling them is an opportunity to screw up by oiling too little or too much. (too little, not enough dirt removal, too much, and the MAF sensor can get screwed up.) Most of us on this site wouldn't have a problem, but I'm sure we all know someone that thinks their a mechanic, but shouldn't be allowed near anything mechanical.

Regarding the oiled media filter issue.....

I have used one on my previsouly owned 2000 model (sold at 170,000 miles) and my current 2005 model (with 120,000 miles). Both = 4.2 V6.

I have never had any problem with the MAF.

I have used oil analysis results showing numbers as good as, or better than results obtained with paper element filters.

I like not having to buy new filters. (The oiled media filter has more than paid for itsself).

I generally check the inside of the intake plenum when I take the filter off, and have never found ANY signs of dust - on either truck.

I respect everybody's decision to buy what they want for their truck. But do like to offer my real world experience for others to consider.

Thanks!

Same here, 63,000 on my K&N drop-in. I have cleaned it 3 times, never a problem. When they say oil lightly, that is what they mean. Some people have trouble following instructions or always think more is better. My truck runs great

Even if you never have a problem with your MAF, there are way to many people that do. Cleaning the MAF is a good fix, but what about the owners who do not know about this condition. K&N came about before most EFI engines, I have no problem with using this on any engine with a carb.

It is actually the right thing to do, to warn people who do not know about possible MAF oiling, AND informing others about DRY element performance air filters. Just like sticking to Motorcraft plugs and wires. We let people know based on our experiences.

Can you feel the 5-10 HP from a K&N?

BUY what you want, RUN what you want, but do consider what new technology is out there.

Any one tried the AMSOIL or the AEM dryflow filter in their CAI? I was thinking about trying one of these since they last a while and require no oil

I have an AFE dry media CAI on my 05' F150 and it works great. All I need to do to clean it is blow it out and wash it in the sink.

IMO the AEM Dryflow Performance filter is the way tho go. Washable, re-usable, and no OIL! Incredible filter. Boosted by mileage from 15 to 16.5 on average just the filter alone. Best of luck for which ever one you all choose.
