Which coils should I use?
We highly recommend buying the coils from us, as there is slight modification needed to make them work properly. If you purchase them from us, we will make the modifications needed for you.
We recommend running authentic Hitachi coils for the GT-R, as they are the OEM manufacturer of the coils that come on the GT-R. The most popular part number for the best performance would be Hitachi (IGC0079). These have been used by the top companies in the industry for many years and have proven to be the best performing and longest lasting option available. There are also other options with Hitachi style connectors. Select your options from the drop-down menu and let us know if you have any questions!
Titanium mounting plates come standard in the burnt finish. To request a certain color please email or message us before purchasing. Please make sure to only clean titanium with Windex and a microfiber towel or a Clorox wipe. Harsh chemicals may tarnish or remove the colored finish.
