I have 12 of these coils. Bought a bunch of parts. These were in there. They are for forklifts if you look at the boxes but looking at the coils shows a number AIC-1355 which after googling shows they are oem Mazda RX8 coils. Forklift application was a Mazda engine so it makes sense.

I have four new in the box and 8 on the forklift brackets.

Is there any value in using these in a custom coil on plug application say on a wedge engine ?
