Ok, I was wondering exactly which way to gap spark plugs to be EXACTLY on the gap that you want?
For example, I bought NGK UR5 plugs and their gap is .039" out the box. I know the preferred gap on our cars (below 20 psi) is between .032 to .035". I found a .034" on my spark plug wire gapper tool, so I bent the electrode (with the spark plug gapper tool) to get it to what I think is pretty close. Feeling unsatisfied , I then ended up getting a feeler gauge (.034") and put each spark plug on my bench vise and adjusted each spark plug so that when I slip the feeler gauge in the spark plug gap area, there is a slight friction made. The fact that these spark plugs also got that V-groove made it a little more vague.
There must be some kind of other way (or professional tool) that will get spark plug gaps EXACTLY what you want without kind of eyeballing/guessing/trial& error method? At the end of the day, it probably doesn't make a difference if I'm off between .032-.035" variance between each spark plug?
