Reply to "Duraspark I Upgrade - Update"

Another upgrade to Duraspark ignitions is to substitute the Ford TFI solid-state coil (the one that looks like a transformer from the next generation of stock ignitions) to replace the can-of-oil coil. This eliminates the common problem of coil overheating and rupturing if 12V+ is left on too long. There are a number of aftermarket coils that work the same but are more expensive than the Ford assembly. Note these coils won't make the engine faster or improve the spark, it just increases reliability.
