Spark Plug Replacement

Hey everyone, I'm new to the forum. I've been reading a lot since I purchased my Cobalt ('08 LT Sedan, 45K mi). You guys are a fantastic resource!

I just changed out my plugs (primarily to get a peek at how the engine is doing). I put in a set of the OEM AC Delco. My questions is, does anyone know the torque specs for this vehicle?

I hand tightened and then gave them a nice tight snug afterward. Do I need to worry about having over-tightened? Would I notice any symptoms of such? I'd welcome any experience.

Cheers.
