So my brother drives a 99 Malibu with the 3.1L V6. We're (I am) doing the plugs wires and fuel filter today. The AC Delco original plugs are like 6 dollars at Napa but the NGK's are 3. Does anyone with any experience with these motors have any recommendations for plugs? I run NGK's in my 3800 but i have pretty much no experience with the 60* V6.
