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.
Same for me
Thé only big difference is the price
