2017 highlander v6 manual says i need (denso 3491) 0.031 gap, but amazon & rock auto says this denso 4705, 0.040 gap fits?

I can't honestly answer your question. I bought for a 2006 Lexis IS350. I've had no issues.

Are these legit products?

Yes, very good original equipment plug in the Tacoma. Had mine in for over 45K now. No problems.
