well , if i was an expert like you then i wouldn't ask too many "dumb" questions , instead i would fill up my gallery...( but definitly not with auto parts , air filter or spark plug .... or over sized bmw ) ...ha... don't dish it out if you can't take it .... i think my question was very stupid for your high level of knowledge and your very creative air filter , i hope you are working on the break pads now because i can't wait to see it next in your gallery regards
