resistor Vs non-resistor plugs/leads M117 engine. HELP!

[johnmcc]

HI all

I want to treat the C126 (1986 5.0) to a new set of leads and plugs, but I'm unsure re resistor Vs non resistor plugs and resistance in the leads.

From what I've read the original leads would have had significant resistance built in, so were supposed to be used with non-resistor type plugs.

My questions is - if I replace the leads with new aftermarket set, will they not have this same level of resistance and should I therefore use resistor type plugs, which most modern plugs are?

thanks

Non resistor plugs should be used and mb dealers are the best for this.... Most aftermarket suppliers default to resistor plugs...

I use them with magnecor leads which I have decided are the best custom leads available..

Aftermarket leads sold by euro etc are rubbish... They stopped supplying real Bosch leads a while back and now they only sell cheap ones that fall to bits after one plug change...
