focus frank Posted December 16, 2010 Share Posted December 16, 2010 Changed the sparkplugs on my focus 1.6 mk1 petrol today and noticed the insulator was an orange colour. Can anybody explain why they are that colour.Thanks in advance. :D Quote Link to comment Share on other sites More sharing options...
tommy.h Posted December 16, 2010 Share Posted December 16, 2010 Hi Frank prob just caused by heat and contamination from under bonnet. nothing to worry about. unless there is excessive oil around the area. tom Quote Link to comment Share on other sites More sharing options...
