duvey 245 Report post Posted September 24, 2013 I've heard really varied stuff about this - the consensus seems to be stick to the factory ones, as they are so easy to replace on the S50 there is no point going with the hi-tech platinum iridium ones, as afaik all they do is last a bit longer. OEM is Bosch 5YDDC iirc. Quote Share this post Link to post Share on other sites
