    I was just curious about what kind and type of spark plugs my truck originaly had in it. Im asuming it was an AC Delco plug. But was it a copper or platnum plug? It has pulstar pusle plugs in it now but I wasn't sure what it had originaly. It says its a vortec engine but because its a 1995 I dont think its a true vortec. But it does say vortec on the valve cover.

    Thanks!

    The Plugs that most likely were installed were A/C Delco.....one of the two below, And the Vortec Engines Run and Perform Better when A/C Delco Plugs are installed.....and for Plugs wires.....once again A/C Delco wires will do the job.
