My '08 King is stock except for s/e mufflers modified to straight out, I'd like the next improvement to be a free flowing aircleaner with a washable element.What is the best ?

I put a screaming eagle on my RC wobble, that way I kept the standard oval cover but gets rid of the restrictive crap behind it.

At the end of the day its up to what you want, standard or custom look.

Don't forget to modify your fuel injection system though, thats when you'll really notice the difference and it will run cooler also.

Thanks for the feed back, sounds like the K&N is the way to go,
