Spark plugs W12
Spark plugs W12
I'm in the process of changing plugs and coils on my 2009 CFSS. I have NGK PZFR6J11 on hand. The plugs I took out PFR6Q. The reach of my new plugs is .15 in deeper than the plugs I'm taking out. I'm not really sure that the old plugs are correct. The part # is 101000063AA and they have a VW logo. Any thoughts?
