Bill, I think the reason for that is, the coil is oil filled. The distribution of the oil helps with the cooling. If it is laid on its side, then the cooling effect of the oil does not work right. I would not mount it on the intake anyway. Too much heat. Don't worry about drilling a couple of holes in the inner fender, heck your not going to live that much longer, you better get that thing on the road. Earl Speaking of Blaster 2 coils, I'm going to be using one with my MSD ignition system. It says in the paper work with it that it should be mounted in the upright position. Has anyone used one and mounted it lying down in the stock type position without any problems? I'd like to mount it on the intake manifold and not have to drill holes in the inner fender.
