Hi All! My 2.0 L engine had fitted Lodge 2HL sparkplugs and according to the PO information it was an expensive purchase some years ago. I don't know if they are originals or not but the time is here for replacement. I see many alternatives looking in the internet and I know that NGK are very popular. However, I would like to know if there are other plugs well tried and tested with good performance in the correct hot range apart from the popular NGK. My engine has high compression pistons (calculated CR is 10.4) with 123 distributor and I use 98 or 100 RON unleaded gasoline.
