Abstract
A spark plug boot keeper assembly interconnects between a spark plug boot and an internal surface of a surrounding structure which defines an elongated spark plug well. A pivoting member of the assembly is located above an annular upper shelf of the internal surface and a circumferential lower rib of the boot. When the boot is properly seated on the spark plug, the lower rib engages the upper shelf. Once engaged, the pivoting member pivots to lock the boot onto the spark plug. The pivot axis lies within an imaginary plane disposed perpendicular to a centerline of the elongated spark plug well.
