318is Plugs ???

[zwerner]

What sparkplugs are correct for a 1991 318is. The manual says NGK BC PR 7ER. Is there an equivalent Bosch plug? I asume this is a three- electrode plug. What effect would I see if a standard plug is used ???Thanks ..

I think Jared is running Bosch Platnums in his 325, but I'm not sure if the six runs the same heat range as the four...

Platinum 4s will work really well in the M42 as well as the M10 in the earlier 318's. However they will not work well in the sixes. Wayne is correct, I run single electrode Bosch Platinums in my car. I used to run the Plat 4's in my old 320is and it took care of a lot of cold-start problems as well.
