Guys what is the best plug for the 165.'? I have always used NGK, When i got the 165 she had Bosch plugs in and she was miss firing. Putting it down to the work she needed i put them back in when i had finished but she still had a miss fire so swap them for an old set of NGK'S i had.Although she is much better and only has,a miss rarely when coldi am going to get a new set. I have ordered a set of Champion copper core are they any good for the 3sgte engine
Denso all the way. Coppers, unless you feel like spending the money to upgrade to iridiums. Platinum is a big no-no with boost. And NGK if you can't get your hands on Densos.
You should be alright, I just try to stick with the OEM when it comes to plugs. There isn't really much to a spark plug, but for some reason some cars don't take well to certain brands. But if it runs good, that's all that matters.
