    Default spark plugs for 2.2 ecotec

    I recently replaced my spark plugs in my 2004 cavalier. I used the
    Bosch ones with the 2 little points, is this adviseable or should I
    change them to the regular one point ones?

    On most vehicles the Bosch Platinum-2s work fine. There are a few
    applications where people report trouble with them, but unless you start
    to have misfiring problems I wouldn't worry about it.

    In the future I would buy NGK or Denso Iridium plugs and change them
    every 50,000 miles. An excellent no worry product if a bit pricy.
    AC-Delco Iridiums are often in fact one of these in a blue box. They are
    specified to 100,000 miles in most applications, but I am conservative
    about maintenance intervals.
