Description
Genuine Bosch wasted spark ignition coil assembly.
Factory coil assembly on Ford Falcon EF and AU1 4.0L (including XR6) models. Also suitable for other 6 cylinder engines using ‘wasted spark’ ignition.
A commonly used wasted spark coil that is retrofitted to 6 cylinder engines in Australasia is the VN Holden Commodore ‘Chocolate Block’ coil set. These VN coils work well in standard applications, however when they are used in other vehicles, most people tend to use spade terminals to connect the low tension ( ve and -ve) electrical connections. Such installations with spade terminals often prove unreliable. Furthermore, the quality of many of the non-genuine aftermarket VN coil packs is not particularly good. For these reasons, we prefer to use this Bosch 3×2 wasted spark coil assembly – not only is it genuine Bosch quality, but it also has a reliable and simple 4-pin plug on the top side (as apposed to the VN Commodore coil pack, which has individual spade terminals on the bottom side).
We also offer the matching 4-Pin connector as an option.
