I used K&N filters on my '74 bus for many years because I had
aftermarket carbs and K&N was the only filter that fit. My opinion is
that they're a pain in the butt to maintain. The only reason you'd want
to use these on a waterboxer would be to squeeze a bit more performance
out of the engine by increasing the airflow but I'm dubious of any
measurable gains here unless you take other steps to increase the
airflow (e.g. exhaust, valves, throttle body, AFM).

Just my opinion. I use the regular paper filters unless I'm travelling
in a very dusty environment in which case I swap in one of the heavy
duty syncro style filters.
