I could only find stuff about the 2.0L

Does anyone know if we can use the same plugs as from a Cavi with Ecotec?

I got a quote for plugs from Canadian Tire and they were 17.99 each!

I mean I'm sure they're good and all but they told me only that plug would work.

Does anyone have or know of someone running different plugs?

I'm not looking for performnace or anything, just replace my stock plugs cause they've got almost 51, 000 kms on them.

Thx.

Yes. The 2.2 ECOTEC in the Cavaliers shares most characteristics motor wise like the Cobalts 2.2 ECOTEC. You can use the same plugs.

Thanks, you just saved me like $50.

NJHK

You're welcome.

I'm going to get a set of stage 1 cams and I was wondering if I should upgrade my plugs when I get them. If I should what kind should I get.

NJHK

It's not necessary but if you want to you can. Your stock plugs are fine or get some Iridiums by Denso.

BlackLS

If I get the Iridiums by Denso should I get colder plugs or should I stay with the same temperature plugs.

NJHK

Same temperature. Colder plugs are more for forced inducted vehicles and vehicles running nitrous.

unless you're doing something where you need to run a heat range hotter or colder or so, just stick with factory oem ac delco plugs made for your car. nothing else will work better.

NJHK

Agreed.

On Nology's page about their Silver plugs they have a chart that shows the electrical and thermal conductivity of the various metals used in spark plugs. Silver and copper at the top. Iridium and platinum at the bottom. They claim that platinum is only used because it's very dense and is needed to meet EPA requirements for new cars to go 100,000 miles between tune-ups because of their resistance to erosion. While I'm always suspicious of a company's advertising, as an electronic tech (though not an engineer), I tend to believe these statements.

Personally, I LIKE to pull me plugs out and clean and adjust them. I used to do it during lunch on a nice day in the company parking lot. I'd like to get some cheap Autolite Copper plugs for the Cobalt 2.2 so that I might gain a MPG or two but no spark plug company that I can find lists a copper replacement plug for the 2.2. I currently have about 25,000 miles on her now. Hopefully someone will come out with an "official" copper plug soon.

that's pretty much all platinum plugs are good for. Lasting longer. But that's why they're so good. Those other plugs while being able to conduct more volts, won't improve performance in any way. The plugs may have a higher capacity, but there's still the same flow through your secondary ign.

Sites like that don't lie. They can't... it's illegal, but they tend to leave things out...

I just recently installed the Nology Silver plugs in my car. The Nology Silver Plugs are resistorless and don't supress any energy from making it to the plug gap. I purchased the Nology coil on plug conversion kit but my ignition control module and the harness for the new remote mounted coil both have male ends. I gotta work this out before completing the install. Apparently the Cavaliers, Sunfires and the Ions were using Iginition Control Modules with female connectors?? We'll see what I come up with.
