DDH, I wasn't implying that you were advocating the use of the trap, just that that was the reason why those cars had the filter system. When I had the canister, it seemed to collect lots of garbage so I jokingly called it the "garbage can". The filter would need regular cleaning before eventually needing replacement and I never drove the car on gravel roads. I wouldn't recommend using the K&N filter since even though you don't drive your car much, what little you will drive may still do some damage to your engine. I have heard about the regular failure of the brackets and mounts but as long as you have a smooth running engine with good engine mounts, it shouldn't be too big of an issue.
