Waterproof NGK is a high quality pest preventer to be screwed on your candle wire.
The difference with the B10F is the diameter of the rubber clamping the porcelain
This one is smaller on the LD10F model so the sealing is much better!
The F at the end specifies the small diameter of the fixing at the end (without screwed end on the olive plug).
Model with 10 kilo ohms resistor included designed for spark plugs without resistor type C7HSA or C8HSA.
For spark plugs with resistors type CR7HSA, CR8HSA, CR8HIX prefer the LB05F interference suppressors for an optimal functioning.
