I don't want to spend a ton on a K&N so I've narrowed my choices to these:

https://www.yotatech.com/~corey/tech...irbox/joey.htm

The first one looks a lot better but seems to be quite a bit more work. I'm mostly concerned about which one will be better performance wise. Thanks guys for your help.

Do em both and you'll basically have your own FIPK kit except it'll be better because the filter won't be completely exposed. If you don't have the skills for the ISR mod then at least pull that spoiler and tube out of the airbox it will yield noticable gains and give you a cool intake sound. It's only like 2 bolts and about a 5 minute job.

The air box mod is really really easy. If you are wiling to go through the work of replacing your stock air tubing, I would just do both. All you will have to do for the air box mod is drill some holes.

Thanks guys, I'll go ahead and try them both. I thought the second one would be much easier but the first one looks a lot more professional.

It's not an either or situation.
The airbx mod will make the biggest difference overall though.
The ISR mod looks cool and will slightly increase power while making the engine MUCH louder at WOT.
