Does anyone know who makes the correct replacement paper air filter elements for the Mr Norms 71 GSS 340 six pack TRI-POWER air cleaners ?. Its a odd size oval air cleaner ive been on K&N and Edelbrocks web site i cant seem to find one. I dont want a generic filter im looking for the original style paper filter any help or leads would be great, thanks Moparts for the free post.
