I have used them for years and feel the car runs better. I use the K&N cleaning kit and their instructions on YouTube and have never experienced fouled MAF issues.
Pros: car runs better, no MAF issues
The reusable filters don’t filter as good as the paper ones you throw away. I can’t understand why anyone recommends drop ins. Just do any amount of research and everything says the OEM style paper filters that are meant to be replaced have a far better ability to filter the air being taken in. I guess the only benefit to the reusable ones like K&N or aFe are the longevity factor meaning you can clean and reuse so they cut down on maintenance cost a little.
Pros: longevity, reusable
Cons: poor filtration

I do not recommend the K&N if you ride in any dusty conditions. The primary reason the K&N flows more air is that it lets more stuff through it. Dust is the last thing you want going into your engine.
Pros: flows more air
Cons: lets more stuff through
I did this to my 7.3 and 6.0. Did I notice anything? Not really. But mechanical and engineering theory it will do something. How is it called a "cold air in take" if its sucking the hot air within the engine bay?
Pros: mechanical and engineering theory
Cons: did not notice anything
First step, if it still has the k&n air filter in it, throw that piece of shit away amd get a decent paper filter.
Pros: decent paper filter
Cons: piece of shit
Best accessory for my Ignis was K&N Air Filter, it really changed the sound of engine which I really liked. Maybe it was Placebo affect but I felt the change in character of the car.
Pros: changed the sound of engine
Vehicle:
Suzuki Ignis
