Zetec Coil on Plug Kit
Spark plugs wires are going away for the same reason that distributors went away.
Vehicle manufacturers want to improve ignition performance and reliability.
Plug wires are an assembly line nuisance, and are often the weak link in today’s distributor less ignition systems. The plug wires must carry anywhere from 5,000 up to 40,000 or more volts to fire the plugs.
This requires heavy insulation plus the ability to suppress electromagnetic interference (EMI). The wires must also be coated with a tough outer jacket to withstand high temperatures in the engine compartment and chemical attack.
As reliable as today’s plug wires are, there is always the potential for trouble. Even the toughest insulation can burn if a wire rubs up against a hot exhaust manifold. The connection inside the spark plug boot between the wire and plug terminal can also be damaged if someone jerks on the wire to remove the boot when changing sparkplugs.
Plug wires can also radiate magnetic fields that may affect nearby sensor wires or other electronic circuits.
Attaching the ignition coils directly to the spark plugs eliminates the need for separate high voltage wires along with their potential for trouble.
Eliminating the individual plug wires also eliminates the need for wire looms and heat shields. That’s why coil-on-plug ignition systems are being used on a growing number of race engines.
Benefits include:
• Directly mounted to spark plug and includes a robust electrical connection to the plug.
• Greater spark energy may allow increase in plug gap for better burn.
• Increased recharge time due to 4 coils.
• Laminations encapsulated in epoxy for environmental protection and increased safety.
• Designed to fit Zetec engine application (both using standard and Cosworth plugs).
• Reduced weight and under bonnet complexity.
• Improved combustion quality and reduced electrical draw.
• losing one will affect engine performance, but you can still drive
As for spark plugs, long life platinum plugs are recommended with the screw off ends.
Similar to those used on the Focus World Rally Car.
Suitable for normally aspirated and turbo engines.
Kit includes 4 coils and wiring to suit.
*Requires aftermarket ECU compatible with running 4 x (0.5ohm), coils
*Kit does not include plugs

All can be sourced through myself
Coils £75 each (x4)
Custom loom with connector plugs to suit £55
£355 for the set up.
Not cheap but quality comes at a price.

NGK 9's will work if they have the removeable screw ends.
I don't supply the plugs with the kit
As for wiring you best speak with Pectel about this as each ECU will be different.
