Does anyone know what the difference is, performance wise, between a drop in replacement K&N filter and a cone K&N. A friend of mine told me that he read in a magazine that the difference wasn't noticeable. I'm wondering what you all think about them. One thing I know is the drop in over all is much cheaper. Think about it, either build or buy the new intake and everything and then buy the cone filter or just buy the drop in factory replacement K&N filter and keep the stock intake. I'm looking forward to hearing what you guys think.

Thanks,
Don
