    2003 Cadillac Seville Performance Parts Reviews

    Average rating:    4.5 - 7 reviews

    Upgrade from OEM Replacement
    In the Mazda 6 2005 Ford engine (factory standard in 2005), originally it had standard Motorcraft copper spark plugs. The Nitrode performance nickel spark plugs are an upgrade, a level or two above the factory Motorcraft spark plugs. As advertised/specified, these spark plugs (which I paired with new TSP ignition coils) did in fact offer better performance/gas mileage (in my case 50% increase in MPG) and smoother running engine. They do run a tad hotter, as specified, with engine temperature just being a tad hotter than what it was before. These plugs do have a drastically different (I think better) design than the factory Motorcraft spark plugs.
