For those of you that have a Weber carb kit with the small rectangular air filter, take note. I looked closely at mine and noticed that the filter media had degraded drastically and I have been sucking straight air for some time. <img src="/forums/images/graemlins/angry.gif" alt="" /> I've cleaned it once since I've owned it, according to manufacturer's specs. I was told it was a reusable filter, but I was never really impressed with the quality, anyway.

I found a K&N replacement for this filter: part# E-3952
The filter measures 6.75"(outside length) X 4.5"(outside width) X 2.5" height
Apparently they make them to order with 2 week lead time.
If anyone knows any other replacement options, please feel free to post...
