Which spark plugs would u recomnd? Champion single or double platinum at gap .50

The best is exactly what it came with from the factory!! (OEM)

DO NOT CHANGE FROM ORIG IF YOU DON'T WANT PROBLEMS

I agree with answer's #1 and #2. OEM all the way, the more the platinum, the more $ out of your pocket. Save your money. I've seen people who think they will get more H.P. or better gas mileage if they buy over hyped plugs.
