Curious. You '05 L26 has blacks, but my '06 L26 has greys.
Irridium spark plugs last 100k mi and work just as well as copper. Copper is a waste on N/A and only lasts 15k mi. Don't use Platinum.
Use 195* tstat unless you can thoroughly explain why not; 99.9% don't need a lower temp.
Almost any oil filter, ever, is of higher quality than ACDelco. Spend $6+.
Yessir, my mom's '06 L26 has black covers as well.
Huh. Is your '05 base or GT? It shouldn't make a difference, since it's the same darn engine, but I'm grasping at straws here.
