Given my conversion from Original Mercedes Distributor(using contact point and pre-resistor to the coil) to EDIS (Bosch 3x2 Wasted Spark Coil pack), should I go for a Colder Spark Plug(Heat range)?
Does wasted spark EDIS generate more heat at the spark plug electrodes(causing pinking)?
Let me know what you think.
Thanks in advance.

Re: Upgrade of Spark Plug
I'd guess the extra spark wouldn't make much difference to the plug temp - it's the combustion which is the main source of that.npk wrote:Given my conversion from Original Mercedes Distributor(using contact point and pre-resistor to the coil) to EDIS (Bosch 3x2 Wasted Spark Coil pack), should I go for a Colder Spark Plug(Heat range)?

Does you engine have a later similar version which uses electronic ignition? That might give a guide to a better plug.

Re: Upgrade of Spark Plug
The later uses Electronic Ignition but still the SINGLE coil with Distributor and Rotor setup.
(My earlier conversion on a Merc also with similar setup, at running temp, I had to retard (significantly) the ignition advance at WOT to stop the pinking(tropical climate)...this lead me to wonder if I need Colder Plugs).
Thanks.
