    Comments about Autolite Copper Spark Plug:

    I use these plugs in our 1994 Cougar XR7 with the 3.8L V6 engine. The engine is still running smoothly with over 125,000 miles, & still gets 30 MPG highway. When replaced, an old set of these plugs were still firing with melted & worn down center electrodes which had a gap of up to 0.012 inch wider than the specified gap of 0.054. These give outstanding service and will keep your car running long after they should be replaced. Excellent quality replacement plugs from OEM with good value for the money.

    Used on 1995 Windstar with 3.8. Must check the gap as it should be between 0.52- 0.56.

      Comments about Autolite Copper Spark Plug:

      The gap of the plug was not correct for the 3.8 ltr engine I was installing it into. I believe the gap is pre-set for a 4 cylinder or 3.0 ltr engine and not pre-set with 3.8 ltr engine in mind. Note: It was suggested to check the gap of a new plug before installation on packaging.
