Which spark plugs r u guys running in your turbo xm. Mine is a 2015 and came with the NGK IR IFR8AG PLUGS. Most of u guys just running the stock PFR7AB plugs and gap.
I'll check Those out.
From what I gather brp only ran the NGK IR IFR8AG plug for one season 2015. They don't even list these in the parts catalog, and shop manual has the pfr7ab listed. Apparently there was lots of fouled plugs with the 8ag.
Thanks
