Yesterday, I was at my friends house and a bunch of them where cleaning their intake filters with an intake recharger kit that I see for sale at auto stores. I saw alot of dirt come off whem they clean it with the solution. Does this work well? or are they better off getting new filters?

 

I think that only applies to reusable filters like the K&N FilterCharger. I don't think you can clean OEM and non-reusable filters.
