I have a JDM obd0 B16a hat is completely stock. I have i/h/e and just bought new NGK plugs, What should I gap them too? The OE is .52 I think but that seems long. What do you think?

0.39-0.44

 

Does it really matter where in those number you gap it? What are the advantages/disadvanges of .39 compared to .44?

thats just the area i would gap the plugs by. By opening up the gap can increase the spark kernel size, thereby creating a more efficient burn. The problem is that any added gap puts more strain on other ignition parts. here are some results to inproper gapping i found.

-Coils may not have enough stored energy to fire, or in the least case, not enough energy to cross the gap, creating a miss-fire.
-Plug wires will break down due to the added resistance as the spark tries to reach ground.
