Brands of spark plugs do not really matter. If they sell it in an autoparts store, it'll make your car run. However, certain brands or styles of spark plug provide better surface area to create the spark, which can lead to better fuel efficiency and improved horse power. Generally, you get what you pay for. For more information on which spark plugs do what, simply go in to your local autoparts store and ask the person at the desk.
Note: Although brands do not matter, MAKE SURE you have the right size.

The spark plugs for any Chevy cobalt are located under the 4 wires that go into the center top of the motor, each one is evenly spread out into a line. Unplug those wires and below them are the spark plugs

take off the plastic cover and under where the silver cover on the engine says ecotech is where the spark plugs are located
under the valve cover.....remove the 4 bolts....lift out the cover with plug boots attached...plugs are way down in the head.
undo the plugs on the plastic grill (the ones ontop) then its a matter of wedging the light back and pulling it up
Spark plugs are a cheap and quick fix if one goes out. The cost to replace one on a 454 chevy engine however can differ depending in the spark plug brand.
There is a plate on top of the engine with four Allen head screws, remove that and the plugs are there, you will need i belive a 10mm socket to take the plug wires off. This is how they are on a 2007 SS i am not sure about what model you have.
If they are platinum plugs, should be every 95,000 to 100,000 miles.
Should be 1 5/8".
They should last 100,000 miles.
