Posting this here simply b/c my car's a civic.

I know dielectric grease is a good idea for most, if not all, electrical connections to prevent corrosion, etc.
That being said(typed), do you people feel it's necessary to use on your spark plugs/plug wire boots?

I ask because I just put on some NGK plug wires and I like the tight fit compared to the old ones which had some sort of grease on 'em and I like knowing there is good metal on metal contact all round. I've also heard of the grease becoming hard and nothing but a mess over time which I want to avoid.
I assumed there was enough of a seal to prevent corrosion on the plugs but not sure.
Anyone actually had trouble with corrosion on their plugs or in their plug wire boots?

Assuming it is a good idea to use it on the plugs/boots, should I also put some where the wires connect to the distributor? Again, I assumed there was enough of a seal there but don't know.

Thanks in advance for any input or advice.

 

:shrug: i think it comes down to personal preference on wire ends...

lots of wires come with a small packet of dielectric grease in the box. the dielectric grease does two things:

1. helps prevent water coming in and causing corosion and poor contact
2. improves conductivity as dielectric grease is highly conductive

i see shops that use it on every plug and shops that never use it. as for the distributor or coil end i rarely see it used there

i guess its more of a personal opinion on this one

 

I use it on most all connections that will be exposed to the weather.

 

Most of the time if you use the stuff that is clear it wont harden up and become flaky (white stuff does)...I have some stuff thats aviation grade and that stuff is great i went through and redid most of my connectors in the engine bay..except the cap, but i dont see where it would hurt anything, after all it is conductive and seals out moisture

 

I have an always will use it on coil towers and plug ends..its silly and lazy not to.

 

i would. sometimes wires like to rip to pieces cause the metal part that connects to wire the pulls out. tony can attest to this, happended to me twice.

 

happens to me as well, Every time i pull a set of Xact plug wires! LOL
F'in Junk.

btw, eric, get me your flanges.. i'm ready to start building your mani

 

where can i find this dielectric grease? any particular brands you guys use?

 

You can get it at any auto parts store, in AZ at checker, autozone, napa, pepboys, etc.

 

Wow, that alone is enough to convince me.

My NGKs didn't come with any but I was gonna stop by advance on my way to work tomorrow and pick some up for my chassis grounds anyway so I'll put a bit in the boots (or whatever they're called). I'll make sure to get the clear stuff.

Thanks for the input everyone, I appreciate it.
