This kit of Factory Ford ignition coils for a BA – BF XR6 turbo and non turbo come as a set of six. The coils supplied by Ford in the early days have been revised and this current coil seems to be a good step forward. Many XR6 turbo suffer from ignition coil problems leading to engine miss fire. There are many cheap Chinese coils on the market but it has been our experience the these coils have very poor results and fail very quickly. Electrical items including ignition coils are not returnable. 000018150
