    Why spend more money

    1 of 1 people found this helpful

    Why spend money to buy more expensive plugs? Champion spark plugs are OEM in Chrysler cars. I had a set of these last over 100,000 miles in a 3.3 V6. The plated shell and threads don't rust or seize in cylinder heads. This is especially important in engines with aluminum heads like the 3.3 V6. These plugs delivered reliable performance until the gap grew to 0.090. They ran for 12 years and 130,000 miles. What more could you ask for?

    Pros: Long life, reliable performance, plated shell that does not rust or sieze
