Spark Plug Heat Shield Removal

[dakota014x4]

im just curious about any long term ill effects on removing those spark plug heat shields on a 3.9 v6. im going to be installing the napa premium wires and just afraid off cooking the boots, thats all. Is it worth removing these things?

Yes, it's worth it.

Yes dim bulb. A pair of vice grips, pliers and elbow grease is all you need

No you do not need the shields. Mine hit the trash 8 years ago. The make changing the plugs a lot harder and trap dirt around the plugs. Grab the shield next to the split and twist in.

I had to soak mine in penetrating lube everyday for about a week straight until they would even budge. Grab em with vise grips and wiggle till they're out.

Why? Just wondering. I mean, if they are heat shields, then they are there to keep heat off something that shouldn't be heated, right? Or no and they are there just because? (not meaning to sound like a smartass, but don't feel like rewording)

the things that are there, get hot anyways, they are there to be a pita (imo), and look like crap too. they are about useless to say the least

Upgrade to better spark plug wires and they are not needed. Plus over time, they end up causing more problems than they theoretically help. They trap dirt and water and cause arcing once the wires start to go.

I ripped them out when I put mopar wires on 4.5 years ago and haven't had them since, no problems. Easier to work on and looks better.

When you install the boots/sheilds, I always put a bit of sylicone lubricant (dielectric grease) in the boot before sliding it onto the spark plug. Makes removing the boot later alot easier.

Hey guys,

I'm having a hell of a time getting the right front shield out. At this point it's all mangled and I'm getting pretty desperate since I can't drive the truck. It's a 2000 3.9L.

What's the no-BS-I-need-this-out-NOW trick on this? I don't have a week to apply and re-apply penetrating lube....did some liquid wrench but it hasn't worked......please...HELP!

Thanks in advance.

get yourself some pb blaster and soak overnight, it loosened up my trailer hitch ball that had been on for 3 years and the nut was rusted on pretty good.

I'll give a try if I can't get it off this morning.....Thanks.
