Are those kits aftermarket kits, or are they "approved" by Kawasaki?
Not that I care much, just curious. ( I already convinced myself it is a good idea to put a cylindrical filter on the engine, without any downside)
Super expensive,. Partly because they replace the air cooiling shroud, which IMO is not needlessly.
I got my kit here:
https://powerequipmentman.com/collections/best-sellers/products/air-filter-upgrade-kit
$180-ish, including an inner and outer filter. You remove the OEM air filter cover, and their bracket screws right into the into the original air filter cover's
existing mounting holes. You could probably piece a kit together from ebay parts cheaper, but you would have to probably drill the air cowl.
What I esp. like about the kit I linked to: you can remove it and put pack the original filter. kit. If heaved forbid I need some warranty work, I can remove the
cylindrical filter kit, and restore the original configuration and none is the wiser. I do not want to waste my breath arguing with Kawi that this filter kit is "OK"
no matter how many ways I can prove and demonstrate that the cylindrical filter works better in every way than their silly little filter they insist on putting on the
FR engines. I lack the time and energy to try to lead any horse to the water, if the horse insists on not drinking.
