Ah hope he ain't drivin' it...ah he won't need a next one.
actually i doubt that. my dad used to run his datsun 1600 without an air filter, cuz he didnt have a choice. he had installed a webber cab and there wasent enough room for a filter so he ran it open. yea i sucked in dust and whatever else, but he had it like that for about 3 or 4 years, and nothing ever happened to that engine. he never even changed a gasket. then he sold it
another thing not to do to yur filter that i wont recommend is using the clamp supplied. that thing cuts into the flange, leaving it disfigured. when u have to remove the filter for cleaning or any other work, u end up loosening that clamp then re-tightening and it does even more damage. my one has some huge permanent 'dents' in the flange. i switched clamps to a t-bolt clamp, which gives a more even clamp and dosent have an uneven clamping surface like the screw type clamp.
this is what my one looks like now:
IMO its worth the extra $30~$40 to get the clamp. in the long run u may have developed a hole in yur flange, which could mean more $$$$$
