Spark plugs 2014 RZR

[Brianrzr]

I have a '14 Indmar 5.7 L 350 hp with about 160 hours. I am going to change spark plugs, what do you guys suggest?

Pull the plug out and get the number off the side and put factory plugs back in it. The factory plug has a burn temp/point and the ecm tuning likes it for eliminating pinging.

The old plugs are AC 12568387. I can not find any info on what to set the gap. Does anybody know? It is really disappointing that Indmar will not publish such specs. I understand supporting the dealer network, but simple maintainance procedures and specs should be available to the owner. BMW does the same thing. I will never by another BMW.

That is an AC/Delco 41-401. They are a laser iridium plug and are pre-gapped, gapping is not needed or recommended because it can harm the electrode. Unless you drop one after taking it out of the box you are good to go. Don't forget the anti-seize.
