A must

Posted by Unknown on 24th Feb 2019

I'm on my 4th CB400F project and I use these on every build. I combine them with Dyna S ignition and they always perform great. One less thing to worry about on start-up.

Coils set for Honda CB400f

Posted by Larry Middleton on 30th Nov 2017

These coils were easy to fit. Excellent quality fitted on a bike with electronic ignition. Bike runs like a dream for a 1975 model.

Great Set

Posted by Michael Morrison on 24th May 2017

Great set for replacing the old worn out coils, wires and caps. Installed on a CB350F. Perfect fit, though the spade connectors come close to the frame and had to be bent slightly to fit in place. Otherwise the bike runs better than ever!

Good product. Keep an eye on the wire colors.

Posted by Tasos on 12th Jun 2016

So these are great but the wire color coding is not like the originals on my 1975 CB550K. Make sure the yellow wire from #1&4 coil plugs into the blue wire on the harness and the yellow wire from #2&3 coil plugs into the yellow main harness wire. Otherwise you'll get a loud backfire noise surprise and the bike won't start.

Good fit, but....

Posted by Jeff on 18th May 2016

So I bought this set up and it is great. Everything you need to get your project moving forward. But... the 1973 CB500 #4 needs the following cap instead of the regular ones included : NGK Spark Plug Resistor Cover - Straight - SD05F. If you have a CB500, order the above cap with the set.

Easy to Install/ High Quality

Posted by Unknown on 27th Apr 2016

This is a great set of coils/ plug wires. Installation of this set was straight forward and did not require any wiring/bracket alterations. My expectations were pretty high (based on previous reviews on this set), and I was not disappointed. I would recommend this set to anyone looking for replacement coils/wires for a relatively stock engine set-up.
