I changed the recipe to 5 Ohm coils after some research, but still need to update the instructions. These are easier on the charging system and do not affect performance. BTW, I also replied to your e-mail message to me.
I installed them and the instructions and fit are great. After installing them I do notice a stronger visible spark. I need to replace the plugs though. They are quite fouled and sometime the spark jumps from the tip of the electrode to the body of the plug instead of the arm. Do you use a different gap with these coils?
