Thanks,

I guess the other thing I'm wondering is whether I have these resistor tips that I see in some posts talking about spark plug wires.

You guys that used the bosch sets, do you have these resistor tips also? Or is it just for original MB wires? What plugs did you use with your bosch wires? Is it like this arrangement.

orig

solid wire- resistor tip- non resistor plug

aftermarket

wire- no resistor tip- resistor plug?

sorry ,still confused, partly due to not having ventured to take my wire and plug out yet.

Thanks, Jeff
