We ordered a foam cover for our stock air filter on my G660. The saw is dedicated to a Logosol F2 plus mill. We found the raincover to be restrictive so we left it off. The saw runs great and we chose not to oil the filter. We take it off and shake it or wash it when needed.
The rain cover to be restrictive? Are you saying the stock air cover? The max flow, and max flow knock off rain covers are wide open and allow tons of airflow
