Seeing so many horror stories (and pictures) of damaged coils these day thought I would post this.   Even the trunk of a car can be a dangerous place for a coil with stuff being knocked around.  This is a good way to protect your coil once and for all.  Take a length of pool noodle and split one side of it to secure the pigtail and cable hardware.  This is the number one killer–having this squashed flat causing the cable to become intermittent.  Then take some bubble wrap, foam neoprene or even cardboard and cover the “ears”.  Secure with two tied elastics.   These coils can be expensive to replace–why take the chance?
