While I'm on a role I thought I would share this with you all.

This is a coil on plug kit for the Zetec / Duratec engine that I have sourced for my car but can get hold of the parts if anyone is interested.

Just to give a bit of technical speel.

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 by a growing number of race teams.

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.

Coils 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
*Wiring depends on ECU configuration
*Kit does not include plugs

Available through myself but they are not cheap.
Send me a private mail if anyone is seriously interested.

 

verybling m8 all the best wiv it

 

Thought more of you zetec turbo guys would want some of these?

 

I'm surprised you cossie lads haven't picked up on using these yet?

 

very trick

do they physically fit a cossie head/cam cover as well then?

do you know if secs s8 can run 4 coils or only 2?

 

Not tried these type of coils on a cossie engine yet but there are several different types of coil on plug on the market so one is bound to fit.

Not sure on S8, it might be worth seeing if it has 4 ignition amplifiers in it as standard? If not the factory might be able to upgrade your ECU with a different curcuit board.

 

They look similar to what you get on the latest CBR bikes. Seems to be the way to go.

 

cool, what is a ball park figure mate??

im guessing lots

 

Depends on type of coil used?

Magneti Marelli are circa £120 each

 

cool post austen just found it.
