Full PnP kit to run one of the absolute best and modern OEM Honda ignition systems in the NSX. The NSX uses a very old design coil with external igniter making the system "dumb" in comparison to modern day inductive smart coils that have a built in igniter and overheat protection. These coils are largely used in the aftermarket industry in many builds as they support 300 whp each coil without ignition break up!

We based this kit off of the NSX GT300 layout and design as it ran them instead of the OEM coils.

No modification or monkey business required, plug it in, put coils in and you are good to go! Kit includes adapter and bolt up bits and full mil-spec wiring loom. Coils are not included.

***Designed to work with K Series coil P/N: 30520-RRA-007 or equivalent, aftermarket ecu, inline ignition dwell modifier, or Prospeed ROM required to update coil dwell***

****Updated design notes****
1. The bolt adapters have gone through a few revisions and are now lighter in weight.

2. The coil seal adapters are no longer aluminum. This is for two reasons, they can get quite hot, and if you ever need to pull a coil on a hot motor you may burn your hand, and they are heavy and sometimes fall off the coil and into the many impossible to reach places of the NSX engine bay. The seal adapter has been redesigned using a nylon SLS construction. This is done on an industrial laser sintering printer, this isn't something that can be done at home and is capable of handling solvents, oils and the engine surface temperatures. The new design is lighter, doesn't conduct thermals, and stays on the coil much better.
