I got my Accel shorty plug for #7 hole under Hooker Super Comp's, but it's still very BAD FIT (0.2" - 0.3" distance, Taylor boot touching header). I'd probably should contact Hooker about it, but the idea of removing header(s) back is very depressing. If I could find a very thin, but still highly dielectric and heat resistant boot for this wire, it will work. Currently I installed Moroso boot and fire sleeve (from Autozone) over it. It stopped fireworks in this area together with miss, but I am sure it will not hold well. I appreciate any help.
