Replacement & Maintenance Guide

Helpful replacement and maintenance guidance for Distributor Cap.

System	Ignition
Description / What It Does	On older ignition systems, the distributor routes spark to the correct cylinder and may house the cap, rotor, pickup, or ignition module. Wear can cause misfires, hard starting, stalling, or poor performance.
Replace / Inspect Guidance	Replace cap and rotor every 30,000 miles when serviceable; inspect the distributor assembly during tune-ups and replace if shaft play, pickup/module failure, or corrosion is found.
Job Difficulty	Moderate DIY
Maintenance Tips	Keep moisture out of the cap, replace ignition wires/plugs on schedule, and mark timing/position carefully before removal.

OK SO EASY TO INSTALL AND IT WORKS REALLY WELL ON MY 1994 FORD MUSTANG 5.0 GT. IT WAS WORTH SPENDING THE CASH TO BUY THIS PRODUCT

This is about the only one with external coil option for a honda motor. Keep an eye on the contact points as they do wear over time and rotor as well. Otherwise good kit and comes with wiring for external coil
