There are many sellers of 'performance' coils, but what do you expect to gain from a 'performance' coil?
Coils are simply transformers - they take a low input voltage and step it up to a very high voltage - the wire is typically stainless steel or high nickel content wire and they are priced from $12 to over $100 - if color is an indication of performance, which is better; blue, red, yellow, orange, green, grey or black?
A coil will not make your engine have more power or run faster unless there is a problem with the old coil.
