Dual Iridium Industrial Spark Plug FB78WW 


The dual-iridium electrodes of Federal-Mogul’s FB78WW spark plug, combined with its patented bridge design and advanced weld process together provide more than two times the service life of traditional  J-gap plugs.  The plugs are ideally suited for fuel-fed, large bore pre-chamber gas engines, where high load and temperature operating conditions are most prevalent. Unlike standard j-gap plugs, the fixed electrode gap construction is stationary during extreme thermal cycling conditions, thus eliminating the need for re-gapping procedures.
