CAUTION! (Prohibited Usage of Spark Plugs)
- Never use DENSO Spark Plugs in the engines for any aircraft, including airplanes, helicopters, gliders and drones. DENSO Spark Plugs are not designed and manufactured for any aircraft: use may result in a plane crash or other accidents due to engine malfunction.
- Never use DENSO Spark Plugs listed in our catalogue in the engines for generators and gas heat pump air conditioning systems. These spark plugs are not designed and manufactured for such use. Such use may result in accidents, including power generation stop or heat generation stop. A separate catalogue for DENSO Cogeneration Spark Plugs specifically designed for generators (gas engines) is available. Please contact your DENSO representative for more information.
- Never use DENSO Spark Plugs for gas burner ignition. DENSO Spark Plugs that we sell are not designed and manufactured for such use. Such use may result in ignition failure or equipment damage due to overheating.
Recommended Torque and Tightening Angle for DENSO Plugs
1. Use the correct wrench for the hex on the plug, and be careful not to damage the insulator.
2. When changing, make sure that the oil, etc. on the outside of the plug does not enter the engine interior.
3. When putting the plugs in, clean the engine side of the flange and put in the plugs after making sure the gasket is in the flange.
4. Make sure the plugs are vertical and tighten them by hand until they cannot be tightened any further (A+B).
5. Then, use a plug wrench to tighten them accurately to the torque or rotation angle showed in the chart below (C+D).
