Hi all, I have a question about spark plugs for a 426 Hemi. I'm told by a coworker that I should remove the crush washers from the plugs before installing them. Just curious if this is true or what your guys opinion is about the subject? The plugs I removed that were installed by the engine builder were Autolite 3924 and still had the washers on them. My concern is whether the plug tube is sufficient enough to seal off the combustion chamber or not? Just wondering what the general consensus is?
