Spark Plug Threading Difference?
Okay, Im replacing the intake manifold, just took the spark plugs out and replacing them with TR55-IX NGK iridiums.
The question is, the threading is longer on the NGK's than the previous plugs.
here is a shot with the mani off... what fun with the strut brace still on.
