Sierra 18-5279 Tune Up Kit for Prestolite Electronic V-8 Marine Engines

The Sierra 18-5279 Tune Up Kit is a complete ignition refresh kit built for marine V-8 engines equipped with a Prestolite Electronic ignition system. Restoring reliable spark delivery starts with a fresh distributor cap and rotor, and this kit supplies both in one package: a Sierra 18-5352 Distributor Cap and a Sierra 18-5403 Rotor, matched specifically to Prestolite Electronic V-8 ignition setups. Worn or corroded caps and rotors are a common source of hard starting, misfires, and rough idle in marine engines, and replacing them together as a matched set helps ensure consistent electrical contact and even spark distribution across all cylinders.

Each component in the kit meets or exceeds the performance of the original equipment part it replaces, giving boat owners and marine technicians a straightforward, fit-specific way to service the ignition system without mixing mismatched parts from different suppliers. Because ignition components vary by engine configuration, this kit is built specifically for Prestolite Electronic V-8 applications; buyers should confirm their engine's ignition type before ordering to ensure proper fit.

Does the 18-5279 kit include spark plugs or ignition wires? No. The Sierra 18-5279 Tune Up Kit includes only a distributor cap and rotor; spark plugs and ignition wires are not part of this kit.

Is the Sierra 18-5279 kit interchangeable with any other part numbers? Yes, the Sierra 18-5279 Tune Up Kit is interchangeable with CDI E66-0029.

How much does the Sierra 18-5279 Tune Up Kit weigh? The Sierra 18-5279 Tune Up Kit weighs 0.45 pounds.

What are the dimensions of the Sierra 18-5279 Tune Up Kit? The kit measures 3 x 6 x 8.13 inches as packaged.

Will this kit work with a Delco EST ignition system? No. The 18-5279 kit is built for Prestolite Electronic V-8 ignition systems, not Delco EST systems, which use different Sierra part numbers.

Is the distributor cap in the 18-5279 kit compatible with in-line 4-cylinder Mallory single point systems? No, the Sierra 18-5279 Tune Up Kit is specific to Prestolite Electronic V-8 applications and is not designed for in-line 4-cylinder Mallory single point ignition systems.

Are the parts in the Sierra 18-5279 kit genuine Sierra components? Yes, both the distributor cap (18-5352) and rotor (18-5403) included in the 18-5279 kit are genuine Sierra parts engineered to meet or exceed the original equipment they replace.

Why replace the distributor cap and rotor together instead of separately? Replacing the distributor cap and rotor together, as provided in the Sierra 18-5279 kit, helps ensure consistent electrical contact and even spark distribution, since a worn part on either side can undermine the benefit of replacing just one.
