tools99 Posted October 8, 2009 Posted October 8, 2009 Just fitted a set of Denso Iridium's Sorry if this is a repost! but just wanted to know if anyone can ellaborate on the benefits/pro's & Cons of Iridiums? The car feels a wee bit smoother to start not much more different apart from that, but the NGK R's that I pulled out seemed to be quite well worn and the white ceramic part of some of the plugs looked a bit brownish/burnt right at the bottom, what does this mean other than the plugs are old and ready to be replaced?

Beavis Posted October 8, 2009 Posted October 8, 2009 The main benefit is that they should last for ages. Quote
Gaz Walker Posted October 9, 2009 Posted October 9, 2009 The main benefit is that they should last for ages. That's basically it yeah, Iridiums last longer than platinum's and significantly longer than copper. Quote
