COPs provide a stronger spark and are less prone to failure than the stock coil pack which typically fail over time due to its location being in a hot area in the engine bay and breaking down over time because of the added demand when turbocharging. The conversion also helps prevent spark blow out meaning you can run a higher boost pressure without causing a misfire which is common over 10psi. I personally experienced this before converting to COPs and since doing so have not had any issues since. The kit also helps massively with access to the back of the head for those who have a coolant reroute installed due to the stock coil-pack no longer being in the way. The loom is made with top quality material and is both bench and practically tested.
Personally run the same kit on my own mx5 which recently made just under 300hp and another on a 400hp car. I can also provide the loom and/or bracket by themselves, just message if that is preferred.
