Edelbrock Coil #22790 is a single coil-on-plug coil designed as a direct performance replacement for the OEM coil on 2008-18 Ford 4.6L-5.4L V8 engines and the 6.8L Triton V10 engine. Each #22790 coil 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. This coil is available in a set of eight under #22791. For the Triton V10 engine, order one #22791 coil pack and two #22790 single coils for a set of 10.
