Dielectric Gel

A silicone dielectric (non-conductive) gel should be applied inside of the spark plug boot, preferably a silicone gel with Teflon added. This serves three purposes:

1.It helps seal the boot thereby preventing moisture from traveling onto the spark plugs ceramic insulator.

2.It lubricates the spark plug boot allowing for easier removal when necessary.

3.It "fills in" tiny spaces between the terminal and the spark plug connector helping to eliminate a possible source of RFI caused by terminal vibration.

•The application of dielectric gel is so critical that Vitek voids the
warranty on any set where the dielectric gel was not used.
