General Consensus .. What are the best spark plugs for the 3.8? Was gonna go with G3 but hear they don't work well for the 3.8..

I just stuck with the stock replacement champion double platinums. At 70,000 miles, mine were worn about .01 larger gap than the recommended .05. Definetly smoothed the idle out.
