    i use OEM Bosch ones. I just changed all of mine. Car starts easier and im now averaging 23.8mpg. Sort of unheard of for any V8 but I just went 160 miles on 6.7 gallons of gas.

    I got Bosch super and no difference, not worse so a good contender.

    Bosch Super is what in the car now... If I had to buy a set now... (I probably do)... then I'd buy from Autohausaz.com... they got the Bosch SuperPlus plug there for under $5 a piece... whereas BMA wants like $7

    SuperPlus is basically the same as Super with longer lasting design.

    Didn't you hear? One of the guy on the forum put Platinum+4 in his 540 and it ruined his engine... plug literally melted his plug thread and only the coil pack is holding it in.

    i have denson iridiums in right now...

    They made a slight difference if any...not worth the extra admission price. Stick with stock.
