What It Does & How It Helps

Glow plugs heat the combustion chamber so a cold diesel lights off cleanly and starts without excessive cranking, smoke or misfire. As they age they draw high resistance or fail open, leaving one or more cylinders cold — the classic hard cold-start, rough cold idle and white startup smoke. A matched set of new glow plugs, with the harness, relay or controller where included, restores fast, clean cold starts and smooth cold-engine running.
