My '72 has the stock oil bath air cleaner. I have a '73 paper element filter coming to replace it. The oil bath has an induction preheating valve on it but from the picture I dont think the '73 has such an animal. Is this finessing with induction air necessary? Or was this an attempt by VW/Porsche to start to clean up emissions? And finally if it is not necessary I suppose that I can just plug the vacum line that controlled the hot/cold/hot/cold flap and have one less vacum line to watch?

Plug the vacuum line, ditch the pre-heat. It was only used on 1972 914s, and I'm not even sure that most of those were originally hooked up anyway...
