Open the owner's manual in look in the back. It will show you the manufacturer's recommended spark plug. Use that spark plug because any non-stock plug I ever used either fouled out quickly or caused the engine to run rough. Forget all the spark plug, "hype ads" on television for more horsepower and better gas mileage because it just isn't true! Every time I get a poor running car with newer spark plugs, it's the non-stock spark plugs causing the problems.
