Denso Spark Plugs

Does anyone have any experience with the spark plugs below in our vehicles? They are marketed as specific to the 5.2 V10, with a gap of .044 which is wider than the .032 I have seen pop on this site. Would you expected to still have to gap them to the factory specs?

I would keep them to the factory gap. Densos are fine. A bigger range of things to think about would be the heat range.

I just use NKG PFR6W-TG (5547) with what ever gap it has out of the box.

Could there be a better choices out there?

Thank you. I will re gap them and see if I notice any difference. I’m sure it is advised to go the the factory ngk plugs, but trying to save a couple of bucks on this project where I can!
