    Plug for the Plugs

    I had a niggling problem with my Hyundai Getz were the engine would sometimes turn over several times before starting and other times would start immediately. changed the plug leads and plugs and it was still the same. On advice from a friend I replaced the standard plugs with the Denso Iridium plugs, and problem solved. Starts first time every time and a lot less wear and tear on the battery.

    It's a good long life spark plug, albeit a little expensive

    Good quality but a little on the dear side
