    Coils, caps and wires

    Posted by Jason Jensen on 6th Jan 2022

    I ordered this product for my 1976 Honda CB 500 twin. Fit perfectly with no modifications. Both points lead wires are blue. Got some yellow electrical tape to indicate the opposite coil. Plenty of spark plug wire to play with and get everything in position. Resistor caps Worked great! Don't forget to use the proper spark plug (ngk b8es) non resistant type. Weak spark if you use a resistor cap with a resistor plug (ngk br8es). Great product everything worked perfectly!

    the coils and caps on my Honda were original and starting to misfire and act up in general so I ordered a set from 4into1. They were easy to replace, reasonably priced and solved the misfire problem. The bike starts and runs smoothly now, Thanks 4into1

    Item was great, bought two to swap them both at the same time. Full removal and install time was less than 1 hour. Swapped my plugs at the same time to give me an end to end replacement.
