Two things to consider. The original single coils may be a bit lower output compared to the mo joe. Also, the fender hot noiseless are great, but they are 2 coils stacked. You have a full sized coil on top, and an almost full size underneath. I had to route my single coil cavities deeper for them to fit. Not hard to do if you own a dremmel and are willing to remove material. This injector is also 2 stacked coils but it's the same height as a normal sized single coil.
