What are the best spark plugs for a VG? I thought that everyone supported NGK plugs which up until yesterday I had in my car.

I was running sluggish lately so i decided to put new plugs in. All I could get my hands on over here were ACDelco plugs. The ACDelco's totally seem to have made my car run 10 times better and alot more responsive.

I know it may just be because they are fresh, but the NGK's only had like 10,000 miles on them.
