Sierra 18-5352 Distributor Cap, Replaces 41058, Fits Ford & GM V-8 Prestolite Ignition

The Sierra 18-5352 is a marine distributor cap built for Ford and GM V-8 engines equipped with a Prestolite conventional ignition system using a screw hold-down cap. It is a fit-specific ignition component that seals and protects the distributor's internal contacts while directing spark to each cylinder in firing order, making it a routine tune-up and ignition-repair replacement part for boat owners and marine mechanics.

The cap is constructed of machined aluminum and stainless steel with a black finish, giving it corrosion resistance for the marine environment while maintaining a precise, twist-on fit over the distributor housing. It measures 5.5 x 4.75 x 3.5 inches and weighs 0.5 pounds. Each Sierra ignition part is manufactured to meet or exceed the specifications of the original equipment part it replaces, and the 18-5352 cross-references directly to OEM part number 41058.

This is a fit-specific part intended for Ford and GM V-8 marine engines with Prestolite conventional (screw hold-down) ignition systems. Because distributor caps vary by ignition type and hold-down style, confirm your engine's ignition configuration before ordering to ensure proper fit.
