Spark Plug Question
Hello to all. I was wondering about the replacement spark plugs for my 69, L46 engine. Manual says for a R-44 or R-45 or R43. I realize the 44 is no longer around and the 43 is to cold but my question is about the R-45. With the R-45 and the R-45s is the only difference the slightly extended tip ? No mention of the "s" versions in the owners manual for some reason. Also is there any benefit to running one of the R-45's over the other? Pro's or con's with either? Thanks and take care.
