Spark Plugs
i just ordered a new set of Bosch plugs for my 89 300E and didn't notice right away that they are a slightly different number than the manuals call out.
Anyone know what the difference is between the HR9DC and the HR9DC+?
Are these still the right non-resistor plugs for the car?
thanks

dammit ... i just noticed that. do you know where/if you can get the non-resister ones? Bosch.
I pulled the plugs to look at them and i had two completely fouled wires. Corroded would be a better description. It doesn't look like they were even locked in. thats what I get for having it done at a crappy little indy shop last time.
