Debate I had with my apprentice about glow plugs yesterday
He swears you should always replace glow plugs in sets of six, but I told him I've swapped singles for years with no issues. His argument was about even heat distribution and cylinder wear, which made me stop and think for a minute. Has anyone else switched from doing singles to full sets and noticed a real difference in cold starts?
