      Comments about Autolite Copper Spark Plug:

      I have already pointed out that this is proper equivalent of AC41-628, not the one on the Advanced Auto web site which is for DOHC SL2

          Comments about Autolite Copper Spark Plug:

          They're Autolite and they've been making spark plugs since my great grandad was a boy. I used these plugs for a scheduled tune-up of my 1995 Saturn SL2 at 200K miles. The gaps were spot on right out of the box, so just bolt 'em in and go.
          Just be sure the crush washer stays on the plug and remember NOT to over-torque!

            Comments about Autolite Copper Spark Plug:

            The plug was a similar to OE. While there are more expensive spark plugs available, this one was like OE and fine for the daily driver vehicle. Replace as standard tune-up.
