True, but.....? |

Going up in HP usually means colder plugs. The RF9YC is a standard plug. The fouling is not what I've seen before.....tisn't a rich mixture (carbon). Hopefully the gray isn't aluminum deposits which can happen when a plug is too hot.....anyway, I am close.....took a long time before this problem became bad. Problem is, I take my car for short drives. Takes about 5 miles before the engine oil is hot enough to have some fun. I suspect if I drove the car harder longer I would see different plug conditions....maybe worse, maybe better....but a clue anyway. Regardless, I was wondering what most of you used out there on FE's that were modified. |
