This product is supplied as a set of 4 glow plugs, sufficient for a full replacement in a 4-cylinder Subaru diesel engine.
If you have experience with automotive mechanics and possess a calibrated torque wrench, installation is straightforward. If you are inexperienced, professional installation is recommended due to the risk of damaging cylinder head threads.
It is compatible with BLUE PRINT ADS71801 and BorgWarner (BERU) GN 116.
The cylinder head is often made of aluminum; precise torque prevents the plug from loosening due to vibration while ensuring the thread remains intact during future removals.
No, these are designed exclusively for diesel engines and will not function in a petrol/gasoline ignition system.
Test the resistance of each glow plug using a multimeter; if the resistance is out of spec, replace the faulty plug.
Check the glow plug control module or relay, as this often indicates an electrical fault rather than just a bad plug.
Stop immediately, clean the threads in the cylinder head using a thread chaser, and ensure no debris is blocking the hole.
Installation must be performed on a cool engine to ensure accurate threading. Always clean the glow plug port thoroughly before insertion.
