- A typical sparkplug (Champion) goes something like RN12YC.
- The R is for resistor, the C for copper.
- Can anyone explain the other parameters?
-
- My car lists an N14Y plug (65 Dodge, slant-6).
-
- Can someone explain why resistor plugs are used now, and how the
- added resistance (I measured the resistance of RN12YC to be 30k)
- effects the whole ignition system? (a 25 year old ignition system)
-
- Could I use an N11YC plug? What is the best available match today for
- an N14Y plug?
