"SEAL-ON" SPARK PLUG BOOTS
BG's "Seal-On" Boots prolong spark plug life because they seal out dirt
and moisture. . .
Engine laboratory tests have shown that when the SEAL-ON Boot is
used, flashover voltage is increased by 8-10KV. Unlike conventional
spark plug boots, the BG "SEAL-ON" Boot is machined from Teflon® to
specific spark plug dimensions and seals tightly on the spark plug
insulator. The boot design incorporates an industry standard type
bayonet connector for ease of installation. The kit includes a Teflon®
grommet that is press fit into the upper end of the assembly so that
the boot is sealed top and bottom - at the secondary lead and at the
plug insulator. Kits are also available for use with "hi-resistance" wire,
which includes the stud and stud support required to terminate this
type of wire (Assembly layout shown on page 49). Optional SEAL-ON
Boot kits are also available for applications where 5/16" ID
silicone hose is used. Available with DSTM connector.**
