HondaVert CPR convert distributor engines B/D/F/H series to individual coils on each cylinder “Coil on Plug”


Hondavert Coil Pack Retrofit (CPR) allows the use “Coil On Plug”, individual coil for each cylinder for Honda engines with D / B / F / H series distributor engines.
This is done by installing an additional device and using coils with a built-in ignitor, for example, the same as used on later Honda models K engines.

Hondavert S300 required for works.
