I orderd new plugs and wires (ALL NGK) for my 280 and they will get to me friday and I will put them in Saturday. Will I have to gap them any more if they are pregapped?

thanks guys

Specific Part Number Spark Plugs will be used in various engines that may or may not require the same "gap".

Considering the cheapness of a Spark Plug Gap Gauge Set, and the little time it takes to set the Plugs to what Nissan specifies for the Z engine, I always set the gap on my new spark plugs. Why? Because then I KNOW they are set right.

Agreed, I think I picked up a simple spark gauge set for less than a few bucks.

Incidentally, my last set of BP6ES plugs was already at the perfect gap according to factory spec.

What is the factory gap for a 280Z?

My plugs are traditional ngks B6ES-11
