It will be used on a 600 cfm Edelbrock carburetor. What density rating of foam should I use? | | | | | Joined: Feb 2000 Posts: 5,215 'Bolter | | 'Bolter Joined: Feb 2000 Posts: 5,215 | Foam is not a good filter element, shop here.. https://wixfilters.com/Lookup/FilterBySize.aspx be sure to pay attention to cfm, some filters are made for lawn mowers and are not meant to have a bunch of air pulled through them. | | | | | Joined: Dec 2008 Posts: 1,922 'Bolter | | 'Bolter Joined: Dec 2008 Posts: 1,922 | With your kind permission: foam not designed to act as an air filter must not be used. No such thing as filter too big. Most people who need to oil foam use too much oil. | | |
