I just won a k&n drop in filter for $18 shipped on ebay. Yes its used but they are going to clean it out before its shipped....anyways

While im replacing the filter im going to do the airbox mod.

What else should i do while i have this take apart?

 

I would clean you MAF sensor while you have it apart. Some elec contact cleaner works good. Also I would pick up a K&N recharger kit....Oil & cleaner...for serviceing your filter. I think they are like 10.00 or something.
