I have an 1993 (E32) 740i with the M60. Which Spark Plugs should I have in it? It had the Bosch Platinum 4 in it I just Replaced them with Auotlite Platinum 2. The difference that I can see is the Bosch has 4 Conductors and the Autolite has on 2.
I can tell the difference in Mileage that the Bosch Got better then the Autolite.
Should I go Back to the Bosch? Is this OEM?
What is the Best Plug I can get in this Car and still get my Avg 25-26mpg.(per OBC).

Thanks

Bosch +4s would probablly be the best. They also last longer than regular copper plugs

I have my bosch +4s on my 93 740 iL, on the dyno, they actually gave about three more horsepower and i have noticed better fuel economy.
