Default spark plug heat shield tubes - keep or discard ?

so i changed my plugs the other day and these heat shields make it take about twice as long as it should.
one of mine was all bent out of whack and fell out, so i left it out.
so what do you think, keep them or ditch them ?

advantages of having them.
1. determined to be important by a DC engineer.
disadvantages.
1. harder to work around.
2. they trap sand, dirt, and grease so you have to blow them out before removing plugs

tips.
put anti-seize on plug threads before installing.
smear di-electric grease on ceramic section of plugs before installing, and then put a little dab in the plug wire boot and smear it with the tip of needle nose or screwdriver to prevent them from sticking and being so damn hard to get off.

common sense says HEAT shield.. meaning it will protect your wires from the heat of the block.. when i changed mine.. i took the extra time to change them over to the new wires.. beats trouble shooting a misfire later on and you not thinking its your wires because they are brand new.

havnt had mine since 03' .. runs great no problems!! one thing you have to do if you pull them off... blow out the hole with some compressed air before removing anything else like plugs or wires.. them sheilds really hold and trap in a ton of crap!

Anybody try reinserted them after they were removed, say with a mallet or something. That way, you could remove them, clean up the area real good, remove your plugs, reinstall the heat sheild, install new plugs, and your good to go.

one of mine fell out and i sort of tried to put it back in. i straightened it out real nice and tried to tap it into the little cavity where the plug inserts, but it was the rearmost drivers side, where the brake booster takes up a lot of room. it didn't want to stay in and i didn't feel like fooling with it. i think they would reseat back into the cavity in the head if you gave it a little smack with a mallet.

i didn't realize until it was too late how much dirt and sand, especially sand, was trapped down in those things. i have no idea how much fell down in the cylinders.

i'm going to ditch them the next time i remove anything.

ok call me a retard.. sorry for butting in.. but i was under the impression you were talking about the shield that went around the wires themselves.. to protect them from the block.. kind of like a wiring harness shield.. my mistake.. i took mine off when i first got the truck.. no need for them.. they are more a pain in the *** then anything else.. just make sure before you pull them.. you dont pull your plug first.. and blow them out with air right after removing the shield.. before pulling the plug out.

Use a good pair of locking pliers and clamp them to one side of the shield, then push and pull on it hard like you are trying to topple the Leaning Tower of Pisa. It will most certainly come loose.


Get rid of them as soon as you can. They serve no good purpose whatsoever! Removing them makes spark plug and spark plug wire removal so much easier.

Mine were loose when I changed the plugs so I just pulled em. As long as the wire isnt laying against the manifold or something else hot it should be fine.

Holly Resurrecting an old thread. Blast from the past and all that............................
2007 to 2014 that is a few years. Funny how even back then most people hated the darn things. I'm still debating if I am going to install mine when I put my engine back in the Jeep. Because it is an off-road rig I am worried about them.
