Got a hair up my ass today and decided to figure out a K&N filter mod. I like how it looks, but with drilling out my pipe baffles and the increased air intake, she is pretty lean now. I should have my Cobra Fi2000 tomorrow and hopefully that will fix the lean situation. Can anyone guess what they are? Big ass crankcase filters that fit right into the stock air intake hoses. Gimme some honest feedback, thanks guys.
