    I really don't know but since Iridium spark plugs last at least 90,000 miles I'd buy the cheaper of the two you mentioned.

    just make sure you buy the brand spark plug that came from the factory. (OEM)

     Laser Series are typically designed to last 80 to 100 thousand miles, where as the Iridium IX® spark plugs are designed to last 40 to 50 thousand miles.

    unless the plugs are hard to get to use the cheaper Iridium IX® if the plugs under the inlet manifold or hard up against the firewall use Laser Series Ive found plenty of times people only use the expensive plugs at the back on v6 using cheap plugs on the easy side.

    The price. I very much doubt the extra cost of fancy plugs can be justified. A fat spark is a fat spark after all.
