EDIT: YES I DO.

--------------

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?

What are they, heat shields? Might be better to keep them.

Apparently those are heat shields . Given the location of the plugs is between the runners of the header, m ethinks you should keep them.

Ah, that makes sense. My stupid brain didnt make that connection, lol, but that purpose looks pretty obvious now. Oh well. Thanks for the info!

If you can save them, you should, but if they give you hassles, then no worries.  My Dakota has them years ago, but no longer.  Makes changing plugs much less profanity laden.
