Was over on RVnet forum reading about pros and cons of K&N air filters. About the time I bought the 94 Burb (June 2016), Camping World was offering a K&N air filter for the '94's for $10. So I ordered one and threw it on. Most of the comments on the RV forum were negative against K&N. I'd read that before in other places so decided to put a new stock filter on. Note that I had cleaned the K&N once.
The results were amazing, immediately more power, particularly towing. And, for the first time over 10 mpg towing, was 9-9.5, never over 10.
As for proof of more power, there is one short, but fairly steep hill on I-5 going thru Bellingham that always slows me down to 50 mph in third when towing. This time it went up at over 55 mph, almost 60, that's a big difference (trailer weight the same as other times).
I have a K&N air filter for sale cheap if anyone is interested.
