spark plug wire clearance
I'm having this same problem with MSD Super Conductors, I figured they might be fine, but I should prob use header wrap or something. Went to the NAPA store and header wrap wouldn't help that much, and $33 for a set of 2 boot protectors was ridiculous. Was thinking about getting a 45* angle pair, but for $100 F THAT.
Found these 2: (I'm currently ordering the second one)
