  • Q:

    what is the heat range (HOT) and how do you compare this plug with AC DELCO Iridium 41-110?

      Yes, this part fits your 2002 Chevrolet Camaro. The heat type for this Platinum spark plug is 'Hot' which has optimum operating range (450°C). A hot spark plug maintains a higher internal operating temperature to burn off oil and carbon deposits, and has no relationship to spark quality or intensity. Part No. 41-110 is made of Iridium and has a higher melting point compared to Platinum however this part is not an ideal fit for your 2002 Chevy Z28- 383.

  • Q:

    Is this price for one plug or for the box of plugs? When I bought these for my Camaro the price was for the box.
