04 Civic Si - Life of Original Spark Plugs?
Just had my car in the shop and the mechanic showed me my plugs. They were nasty: The electrodes were worn down and black as was the entire base. Obviously, I had them replaced with new Iridium plugs. The manual states that the OEM plugs are good for 160,000KM but the car only has 66,000KMs on it. The mechanic didn't think much of it, but should I be worried?
