I've used K&N filters for two decades but this aftermarket cold air intake for my 200 Miata came with a foam filter which last only a couple years, Fitted a RU-4870 on the mass-air-flow and it works flawlessly. Ordering the filter direct from K&N was easy and it arrived quickly. Great deal all around.
