plugs

So I got my ruthenium spark plugs from an authorized NGK source (ngk.com). I got the right part number (verified several times and with tech). When I went to do the job I compared the old to the new and the NGK plug is several mm taller...wtf? This can’t be normal, can it?

I haven't seen anything come up on my searches for ruthenium spark plugs so forgive me if this has been posted before. My question to the community is what do you think about these new ruthenium spark plugs offered by NGK? Has anyone tried them on their raptor yet? I'm asking about 6.2L...
