This coil pack can also be used to replace the OEM coils on 6.8L Triton V10 engines however you must add two additional single coils (#22780 x 2) to replace all 10 of the 6.8L coils. Each #22780 coil and #22781 coil pack features advanced technology with heavy-duty primary and secondary windings inside of a corrosion-resistant housing. The enhanced windings in these coils offer higher energy and voltage output for greater spark and can help to provide quicker starts with improved idle quality. Coil housings are resistant to heat, shock, vibration and corrosion.Edelbrock Max-Fire Coil On Plug ignition coils are designed with higher resistance for increased energy output at higher rpm, when compared to an OEM coil. They're ideal for use with turbocharged and supercharged applications or engines that have been converted to E85 fuel. The coils are sealed with a high temperature epoxy for shock and vibration resistance—as well as excellent thermal conductivity. The spark plug spring contact is made from stainless steel, with a ferrite lug to reduce EMI/RFI noise; while the boots are molded from a high temperature silicone compound for superior heat resistance up to 550 degrees F.
