I just bought a set of Denso platinum spark plugs for my 4th generation. I had the bosch platinum +4 plugs on my last Max, and they didn't need gapping. Do these Denso plugs need to be gapped? If so, to what size?

Even plugs that come pre-gapped should be checked before installation.
They are almost never consistent & correct.
