K&N air and oil filters are at the top of my list.  They trap more particulates than any other filter brand that I've ever used. To top that off you never need to buy a replacement air filter ever again, just simply wash, dry and re-coat them and it's back to being new.  In my opinion they should be a standard item in all new vehicles sold today.  Improved, clean air flow means a cleaner longer lasting engine and since you never replace it, there's nothing to discard.  It's good for your vehicle, gas mileage and for the environment...that's a trifecta in my book!
