Waiting for other mods so I only have to tune it once.

Those K&N filters are garbage, they just have a great marketing campaign. They don't filter well. Guy's who ran them on diesels doing oil analysis saw worryingly large increases in damaging contaminates with them. The oil from the filter contaminates you're MAF sensor making your engine run poorly. And then it's not sealed to the radiator support like the factory box so instead of getting cool air, you're sucking the hot under hood air, costing more power. With the factory box sealed there's also a slight ram-air effect because of the high pressure area behind the headlights when you're driving. That factory Marauder setup, with a basic paper filter, will flow more than enough clean air to support 500hp.

K&N's are good for what they were designed for, race cars that get the engines inspected and torn down regularly.

I have an 08 with the K&N panel filter. When I first opened it from the plastic it came in, I blew off the excess oil from the filter and installed it. I have since cleaned it twice with their cleaner and haven't exactly re-oiled the filter before reinstalling it into my cvpi airbox without any issue's. She's a totally stock ripper.
