Anyone know what the correct spark plug gap is for the M3W I just changed my champion RA8HC plugs. One was set at 28 and the other at 30.
I put in NGK DCPR7EIX and out of the box they are 28. I put them in as out of the box 28.
I dont see any difference between the two. Seems to start the same and took it for a short
drive. All seems normal. My old plugs only had 3300miles but I read on a face book users page
that the NGK plugs help with starting. My old plugs still look good so will keep them as spares.
