K&N drop in filters
Thinking about picking up a few of these and throwin em in to see what they do. Some people seem to like them some think they do nothing. Are they ready to go out of the box? or do I need to oil them like i've read? or do you just oil them when you clean them? I've got about 28k miles on my stock filters so they've gotten some use at least. Also with my fast intentions exhaust and if i install these filters do I need to get a tune? I don't think I would with just those 2 things.
