Sierra 18-5277 Tune Up Kit for Prestolite V8 Single Point Distributors, 12 Volt System

The Sierra 18-5277 Tune Up Kit is a complete distributor service kit built for Prestolite V8 single point ignition applications using a clip cap distributor. Designed for 12 volt systems only, this kit gives you every wear part needed to restore reliable spark on a Prestolite single point distributor in one purchase, rather than sourcing a contact set, condenser, cap, and rotor separately.

Inside the kit you get a Sierra 18-5303 contact set, a Sierra 18-5347 condenser, a Sierra 18-5369 distributor cap with gasket, and a Sierra 18-5407 rotor. Each component is engineered to meet or exceed the performance of the original equipment part it replaces, and the kit ships in a display package for easy identification at the point of sale or in a parts inventory. Because ignition tune-up parts are fit specific, confirm the part numbers above against your existing distributor components before ordering to ensure proper fit.

This kit is intended for inboard and stern drive marine engines running a Prestolite single point distributor with a clip-style cap, and is suitable for salt water use environments where corrosion resistance and reliable ignition performance matter most.
