about 2 months ago i did a tune-up on my car and installed ngk iridiums...
last week i was bored with a plug socket in my hand and took one of them out to see how they were looking...accord to the spark plug guide in the back of my buddies shop manual my plugs have high speed glazing which means either its running too lean or too hot... and as a side note they said "switch to cold plugs if driving habits warrant" now what does that mean to me exactly? would a colder plug be a good idea? and how do i find a colder plug for my car?
