Kent, weren't you on the Vanagon list? Good to see you in a diesel GL. I've been wanting one for years and just bought an 07 last week with close to 100k. Looked on ebay for air filter and can't seem to figure out which one is correct. Saw a youtube vid with a large cylindrical air filter on an 06 CDI and thought it must be the same, then not sure. Can you point me in the right direction? Thanks.
