Do I need to keep these?



I’m changing the spark plugs on my wife’s grandmother’s 2003 Buick Lesabre. They plug wires have these weird metal tubes with a spring on the end covering the plug boot, and made getting the plugs wires off a pain in the ass. I found that they slide right off the plug boot and aren’t attached in any way. Do I need to keep these on? Or can I toss them and just put the plug wire back on with just the rubber boot on the plug?
