Review on 🛡️ JDMSPEED Black Shield Protective Sleeve by Paul Monzon

Used on Chevy Silverado with Kooks terminals and special red spark plug wires. It's impossible to put them on spark plug ends and metal guards without cutting the round wires. It wasn't easy to cut the wires, which caused part of the sleeve to unravel a bit, but this isn't visible. Looks well installed and still seems to be holding up and working as intended. Updated August 20: Pretty useless. Some turned white from the heat, I doubt they did anything.
