justbeen on motorsport developmentssiteand they have coil pack conv for£400 are they worth doing whats the advantages

 

They are a very good idea if you need one, rather than want one!!
If you have no misfire proplems, you will not likely see any or much benefit, thoguh will most likely make it smoother.
However if you plan future upgrades, and loads of boost it will be more liklely that you may run into the spark being blown out so this would then be necessary.
If sticking to stg 3 or so I would just bung on a group a coil.
Depeding on your driving style a CLOSED LOOP might be wise investment from STU as these can be very good especially for long distance stuff.
