Ceramic Seal-On Extensions Extend Spark Plug Life In Demanding Applications Engine laboratory tests have shown that when a tight fitting spark plug boot is used, spark plug life is increased.
Now BG introduces a composite ceramic – teflon extension that incorporates a teflon coated VitonTM “O” Ring for increased sealing pressure.
Because the voltage necessary to “flash-over” the plug insulator is increased, spark plugs will operate at larger gaps that previously resulted in plug failure
High alumina ceramic prevents dielectric breakdown due to corona cutting.
VitonTM “O” Ring increases sealing pressure, yet makes extension easier to install.
Patented DSTM Connector uses a double spring and will not loosen like rajah types.
Model available for use with silicone hose (stud connection).
