No...the Kubota snorkel fits directly onto the box holding the air filter. Existing filters not disturbed. However, dust entry into the filters is reduced by about 95% or better in my case...nothing but dusty roads here on my place...IMHO, this is a design problem...vehicle should come with snorkel standard and as part of the roll bar...terribly expensive part, but gotta have it unless you are really handy in fabricating such...even then, it would be best if you saw one installed before you try to fabricate one yourself.
