Spark Plugs
Anyone know what the difference is between the HR9DC and the HR9DC+?
Are these still the right non-resistor plugs for the car?
thanks
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.
