Either, all day long. Just make sure NGK is an Original/genuine one!

I torque my spark plugs with my ring finger 3 inches away from the socket, halfheartedly. Seems the be the perfect torque for every spark plug.

There are fakes of both brands, be careful out there.

Another vote for NGK. Never had one go bad prematurely, and usually the second or third cheapest plug avaliable for most vehicles.

 

[The Critic]

13 ft lbs, but with anti seize. Not sure why.

 

[JeffKeryk]

I squirt a little WD-40 down the plug hole to clean the threads.
I use a little anti-sieze on the plug threads.
Of course, both of these lubricate the threads.
I start the plug by hand with a rubber plug installer; thread 'em all the way down by hand.
If there is any resistance something is wrong!
Chase the threads if necessary...
Torque them to 13 pound/feet.

I may be over-torqued...
But I have never had a problem.
Oh yeah, don't forget the dialectic grease.

NGK or Denso?
Wifey's 2006 TSX came from the factory with 2 of each...
All good either way.

 

[mobilaltima]

thanks for the info guys. Never thought to use anti seize, but ProDemand looks like an OEM type information website, so i'll go by what it says.

 

[ZZman]

How tight is 13 ft pounds? Is that like snug or really snug?

 

[MarkM66]

I go by the instructions that come with the plugs. I think it's usually seated, then another 90, but would have to double check....

 

[BlueOvalFitter]

I usually tighten them until the back end of the vehicle starts to move sideways.

 

[JeffKeryk]

The torque depends more on the cylinder head material. Those of us who grew up on iron headed big block high compression need torque wrenches. Don't ask me how I know...

 

[dogememe]

I just tighten it by feel and have never had a problem in quite a few vehicles including newer ones with aluminum heads.

Denso plugs are great, as are NGKs.

Put a little anti-seize on the coil boots where they go over the plug body, as well. They become very difficult and time-consuming to remove after getting stuck to the plugs.

Yes... on those

All others have been TFAR (That feels about right)

NO!!! you use a dab of di-electric grease or silicon grease or "spark-plug boot greases"; yes they sell that in the store.

anti-seize is the wrong lubricant for that application.

You can use KY Jelly on it for all I care. Anything is better than having the coil boots stuck.

Not really. Doesn't all anti-seize have metallic particles? That would be less than ideal for a spark plug boot.

And KY Jelly will dry out and no longer be effective. Dielectric grease is the proper material for this use.

 

[Vikas]

Come to think of it, if you had told OP to use KY, I would have not piped in.

 

[MaximaGuy]

Engine oil on the threads and remember they are coarse threads, they are tightened snug and don't need any more torque

Do not do this. That can cause a pathway for misfire. Anti-seize is a metallic grease, you want to keep that off the plug porcelain and boots. You need to be careful not to have it all over your hands when handling spark plugs. Just a bit on the threads. Don't over-tighten then when using anti-seize i think its 20% less torgue when you do. I do mine by feel anyway.

Dielectric grease is what you want to use on the boots.

on my old 392 Hemi with the 3/4 reach plug and crush washer. i would stop when the crush washer stopped crushing.
