The K&N KA-9006 is a rectangular, drop-in replacement element for the stock air box on the Kawasaki VN900 Vulcan Classic, Classic LT, and Custom. It is custom engineered to fit the specific application and is designed to provide low restriction. Its pleated media provides a large filtration area offering long service intervals, and multiple layers of woven cotton gauze media offers excellent filtration. Compared with a disposable paper stock element, this cotton-gauze oiled design is the kind of reusable upgrade VN900 owners search for as a Vulcan 900 performance air filter.
The main reason to pay more than a stock filter is that the element is washable and reusable. The manufacturer states washable & reusable, pre-oiled and ready to ride, and the filter carries a No-Hassle Lifetime Limited Warranty. The manufacturer also claims increased horsepower and torque, but it does not publish a specific gain, so treat that as a claim rather than a measured number. Owners on user forums report a quick install and say it avoids buying another disposable filter at the same price.
Fitment is listed by the manufacturer for 2006-2018 VN900 models, but sources differ on exact years, so confirm your model year before ordering. For DIY work, the manufacturer rates installation as easy and estimates 5-10 minutes with a screwdriver. Keep the rubber base seal seated, since the rubber seal around where the filter installs over the intake is easy to damage. Re-oil with the manufacturer's recommended amount of 0.45 oz (13 ml) after each cleaning.

The manufacturer rates this filter as an easy DIY job that takes about 5-10 minutes and typically needs only a screwdriver. Before installing, inspect the rubber base seal and make sure it sits evenly on the intake so unfiltered air cannot bypass the element. Owners on user forums advise handling the seal carefully during reinstallation.
