I try to support my local kawi shop and just get OEM Filters and Oil. Price is not all that different and I like to look at the bikes while i am there. You should be able to find oem filters on amazon. As a small business owner myself amazon is a big reason why our local shops are on the decline. Also my local kawi shop usually will give a me a %10 discount because i visit them often. Can't hurt to ask.
