Ignition Coils and Caps

Posted by Darrell Jennex on 13th Jul 2022

I have installed these new coils and caps on my 71 Honda CB500 which replaced the original equipment. The original wires on the old coils were hard and weathered effecting performance. This was apparent once they were replaced with the new coils and caps from 4 into 1, the idle is smooth and acceleration very progressive with power delivery as expected. Thanks!.

Perfect Fit

Purchased new coils and spark plug caps for my CB400f. Perfect fit and high quality. Lots of length on the HT leads to route to my preference. Didn’t completely solve my performance problems, but they needed replacing.
