A protective boot for an ignition system component housed in a housing having a base with a cap mounted thereon. The cap is of the type which is formed with a plurality of upstanding towers formed with passages for receipt of electrical leads leading from various electrical components in the ignition system. The boot includes a flexible jacket for closely fitting the cap and a plurality of flexible inverted cups for closely overfitting the towers and projecting beyond the upper ends of such towers to form respective nipples defining bores for passage of the electrical leads. The nipples are formed to closely fit the leads to form a seal therearound. A flexible skirt is formed by the lower extremity of the jacket for projection over the joint between the housing base and cap whereby the boot may be installed on the housing to form a tight seal around each of the electrical leads and also over the joint formed between the cap and base to thereby positively seal the electrical component against atmospheric dirt and moisture.
