<p>A bonding cap (2) has a tip release hole (22) at the center, fixing legs (23) spaced along the top portion and pointed-topped discharge dots that enable concentrated discharge. The bonding cap is mounted over the central tip (15) of the spark plug (1) and defines a room that functions a precombustion chamber (3) forming spaces (31) between legs to enable good heat radiation and smooth air flow.</p> |
