I saw an Ad in Dirt Rider this month for AFE Air Filters http://www.powersportsuperstore.com/ADVANCE-FLOW-ENGINEERING-ARIES-AE2-INTAKE-KT-YAM-W-p/tr22-9116.htm Have any of you heard of these and if so, do they work? I am all for making the air filter cleaning job easier, but I'm not sure how well these work. And if you look closely you gotta wonder how well they fit in the airbox. I am sure they are similar to K&N filters, but I haven't heard how they work next to foam either. Any advice would be great. I know this could end up being as controversial a topic as engine oil, so I'm sorry in advance if this turns out to be a long thread.
