stapi Posted April 12, 2010 Share Posted April 12, 2010 I have done a bit of a research about that myself recently, most sources generally say that a sparkplug is just a sparkplug and there is not much difference between them. The fact is that some of them are a bit better quality and will last longer but you can’t really expect any difference in ‘performance’ (please correct me if I’m wrong). I ended up buying DENSO Iridium, I’m happy with them, but to be honest can’t see any difference compared to standard NGK ones I had fitted previously.
