Frequently bought together:


The Harnessed Performance 1ZZFE Coil-On-Plug (COP) conversion harness for the Mazda Protege plugs directly into your stock ignition coil plugs and converts your system to an individual coil per cylinder that fires in wasted spark setup. This is a plug and play harness that does not require any added steps to install. 

Currently available for conversion to Toyota 1ZZFE coils. Coils are not included with purchase. 1ZZFE coils are larger diameter than the factory Protege coils, therefore a 626 valve cover or modification to the factory valve cover is required to accept the new coils.

A conversion harness to other coils can be manufactured upon request, please contact us for pricing and lead time.
