I wouldn't even think of cheapening out when it comes to sparkplug, I'll go Iridium most of the time and you don't often replace them anyway and the benefits outweigh the savings you are trying to make with.....stay with OEM NGK or Denso japanese plugs.I've been looking for replacement sparkplugs for my 2018EC apart from the very expensive OEM do NGK OR BOSCH and so on supply any as I'm coming up blank. Has anyone else had this problem 🇬🇧🇬🇧
What I have found his that no sparkplug listings show an alternative to the OEM sparkplug. Being the the cross has been here for three years now I find it very strange, perhaps their made of gold as the cost of replacing them could cost about £160 for four sparkplugs and that's fitting them yourself. If anybody has any info please post a reply in the meantime I'll keep looking.
