I've used K&N filters for years in several of my vehicles. I have a K&N filter in my '03 Sport Trac. According to K&N, their filters work better with a bit of dirt on them. So, it's been sitting there for 11 years and never been cleaned. I check it once in a while for any build up of dirt and give it a few taps. They are very reliable and filter forever. Never had a problem with them and only ever cleaned one once. Took a few hours.
