My question is i was told you cant set the gap on the dual type plugs that they were already pre-gapped is this right or can you gap these plugs?

This is the plug we're talking about:
NGK BKR5EKB-11
While not the V6 plug, this is similar:

From www.ngksparkplugs.com , "...While it is a popular misconception that plugs are pre-gapped from the factory, the fact remains that the gap must be adjusted for the vehicle that the spark plug is intended for."


With that said, the -11 in NGK's part number indicates that it is pre-gapped at .044, and all the NGK's that I've checked were right on spec. To me, this was close enough to .043, and I installed them without changing.
