Coil and spark plugs

Although used coils all look alike, they should be viewed with suspicion since one cannot tell from the outside whether and how often they were exposed to overheating in the past. Installing the 123ignition system will ensure that the coil will never overheat again in the future. Of course you can also order this here. Below you will find a picture from the coil we recommend at ‘Accessories’ and you can easily add it to your cart.

Perhaps you will also need new spark plugs? At 123ignitionshop we’ve added the spark plugs most commonly used in addition to the 123ignitions we offer. See: the spark plugs list.
