Jamie 1 Posted June 7, 2017 Quick one gents - just gonna change my plugs and is it best to do it with the car hot or cold? Quote Share this post Link to post Share on other sites
Jon_vr6 1 Posted June 7, 2017 If your just doing plugs I'd say cold otherwise your going to be burning yourself on the manifold. Sent from my SM-G930F using Tapatalk Quote Share this post Link to post Share on other sites
Dox 23 Posted June 7, 2017 I'll say hot, alloy expands greater with heat than steel. In practice the won't make much difference. Quote Share this post Link to post Share on other sites

Jon_vr6 1 Posted June 7, 2017 I always do the oil as well so engine is usually hot when I do it. But thought it wouldn't make any difference if just plugs Sent from my SM-G930F using Tapatalk Quote Share this post Link to post Share on other sites

I think I'll just wait til I'm doing the oil and do them at the same time. Quote Share this post Link to post Share on other sites
