I've never spent money like that for an air filter, and most likely, never will. But I know they're sold for these trucks/engines. I know a lot of people that like them, and more that really didn't notice much, if any difference.

The reason they allow more air flow is because they don't stop as many particles!

Run away from them.

Food for thought ....... when I bought my new '02 F250 PSD I took it to a chassis dyno in So. Cal. We ran it with and w/o the K&N filter, these are rear wheel numbers. Without the K&N filter using the stock part it hit 197 hp @ 3,000 rpm, with the K&N filter it hit 212 hp @ 3,000 rpm. WOW!!! huh .....but up to about 2800 rpm it was just about the same for both. I know you have a gas rig and it may be different for you but who is going to drive around town in a diesel at 3,000 rpm all the time to get the benefit (?) of the K&N. I run nothing but Ford filters now.

I am using an AFE dry synthetic drop-in air filter. I always had great oil analysis on my '01 7.3 using the same brand and type of media. I prefer the dry filter because it eliminates the possibility of oil contamination of the MAF sensor and cleans easily with dish soap, or Simple Green, and water. I put the OEM filter back in while the filter is drying, if necessary to drive my truck.

K&N filter opinions are like which oil is better.
My 2013 is running out of the initial bumper to bumper warranty. I don't use the dealer except for warranty work. I usually take it to an independent ASE ceertified mechanic shopin my area that has an excellent reputation and service. I asked about using a K&N filter as I had used one before on another vehicle. This mechanic advised against it arguing that Ford spends millions designing these vehicles that provide an air filtration system that keeps out harmful debris meets engine airflow requirements and sound. The oil you add to the K&N can collect in your Mass air flow sensor.
Unless you are in competition it doesn't make sense.
wait while I put on my flame retardent suit.

I use one in every car I have. Used them for years and did have a map sensor go out one time on a 4.6 mustang because of the oil off a brand new out of the box kn filter. SO it does happen, but rarely and only if over oiled.


Do I think I get any performance, no, just easy to clean and pays for itself in a few years. My cars stay 5-12 years on average and I clean it as needed. No set time of milage, as I don't put more than 7k on any vehicle a year.


As for Harley motors, everyone changes to a SE (Screaming Eagle- their hi performance brand) and some new pipes. This is cheapest extra 10 hp on a Harley.


Thousands upon thousands use them, so I don't think Ford throw aways are any better or worse.
