I've been using Autolites, with no complaints, but is there something better? I tried Bosch Platinums, JUNK!!!! NGK is the direction I'm heading. My question about NGK is V-Power or GP(platinum)? From this list: http://www.sparkplugs.com/results_app.asp?...=1&AAIA=1011845 which would you choose.

My cars are BMW 1989 325is and 1991 318is
