This coil kit has been specifically designed as a direct drop-in replacement for the OEM Barra coils that simply cannot handle increased power modification.
These coil kits incorporate our off the shelf big-hitting R35 GTR (Smart) Ignition coils that have been proven to make north of 2600hp and void the requirement for the genuine inbuilt ECU ignitor system. (Note this kit will only fit the FG rocker cover, the FG cover does fit the BA-BF)
As these coils have different windings to the factory coils, your ECU will require the correct dwell time to be set to fire at their optimum performance rate. On flashed later model OEM computers (FG onwards), the current draw on the internal MOSFETs are monitored for coil failures. This calibration will also need to altered as the current draw on the MOSFETs are significantly less load and may trigger a false misfire error due to the current load being focused on the R35 smart coil instead.
