And I on the other hand don't think it is too bright to take perfectly good plugs out and throw them away!! What the results are at 108K is NOTHING has changed! The same milage and no change in the engine responce. So changing them even at 108K did NOTHING for the engine performance.
The thing passed smog at about 104K. The reason I did change them is the wife thinks she can hear some pinging from time to time.. THAT did not change with the new plugs.. My old ears cannot hear any pinging but she says "listen to that! can you hear it?" No I cannot! But she still says it is doing whatever the noise is.
