“ When I switched to the O’Donnell glow plugs, the first thing I noticed was how much better the engines seem to idle. Even before tuning to the new plug, the idle was immediately smooth and consistent. These plugs also seem to provide a little bit of extra snap on the bottom to midrange of the engine, and I can say that I actually gained run time with these plugs! Almost 30 seconds a tank in back to back testing!”
