I'm going to rain on the K+N parade because they did not add horsepower over a stock filter and they did not filter as well which is, after all, the point of a filter. Yes, the oil traps some particles but you can see the pores if you look at one with a light behind and that can't be good.
I used to use one years back but after finding gritty dirt and grime in my velocity stacks and on the top of my carb body, I tossed them and went back to "paper" filters. Just my opinion and experiences.
Go with a quality paper filter.
