Anything Else??
Also, which seems to last longest.
Thanks

As far as a standard plug goes the threaded part of plug is too short on the OS plugs. The LC3 is the longer OS plug. Most people i know that run standard plugs use OD99's or other OD plugs. I'm not qualified to answer that question since i've never owned or worked on a non turbo plugged engine.
