Looking for a part number for VQ copper plugs
 

I've searched for all variations for copper spark plugs, copper plugs, V-Power/370Z, etc, and all I find is people mentioning that you can use coppers, but they use Iridium GTR plugs, or something of that nature. So my searches have been fruitless. And since copper plugs are not recommended for either the 370Z, G37, or GTR, they don't pull up as an option in parts catalogs. But I'm sure they exist, they're just not tied to any of these cars in any searches.

So here's the question:

Can someone please post up a part number for copper spark plugs in either stock or one step colder heat range?

Thank you!

Call NGK, the tech support can help you. They may not make a copper spark plug for our platform.

This is off of the NGK website.

Copper spark plugs” is a term mistakenly used for a standard material spark plug. A standard material spark plug traditionally uses a nickel-alloy outer material fused to a copper core. Almost all spark plugs use a copper core center to conduct the electricity, jump the gap, and promote heat dissipation. However, as an outer electrode material, copper would not be a good choice, as it is soft and has a low melting point (resulting in a plug that would last minutes, not miles). Nearly all NGK spark plugs, including precious metals iridium and platinum, have a copper core. When one talks in terms of nickel alloys, platinum and iridium, one is referring to its durability, or how long a spark plug will last before it needs to be replaced. However, when one talks about copper, he or she is referring to its ability to conduct electricity that is needed to fire across the gap and ignite the air-fuel mixture.

I know what he is up to. There is some internet grumbling going around about copper plugs vs. Iridium/Platinum plugs. Been going on for years. It's just silly. Same thing with Ethanol in the fuel, etc.

I'm just looking for $2 plugs! Their new Ruthenium (sp?) plugs have a copper core, better than blah blah blah, but they're pricey like everything else. I'm just looking for something cheap to keep me going until I can do my engine swap. On this engine, low compression keeps fouling plugs, so I don't want to spend $$$ on 60K mile plugs when I go through them so fast.

Can't blame you for that one.

Check with Rockauto.com, they have a huge selection for cheap if you can wait a couple of days for delivery.

You can maybe use some carb cleaner to clean them up a bit.
Just a thought. I'd try that before i went sticking plugs in that don't belong in these.
