        NGK Spark Plugs

        I recently purchased a set of NGK spark plugs from you. I have a previous experience with the brand in smaller engines, which is why I selected the brand for my Mustang. The plugs have dramatically improved the performance of my engine. A very good purchase at a very fair price!!

        Great maintenance upgrade.

        These have made my idle smoother and improved my throttle response. Great investment at just a little more money then lower grade spark plugs. Overall these are a must have to keep your Mustang healthy.

        5 1990 GT - mylilpony Installation Time: Afternoon

        Works GREAT

        I changed my ignition coil to MSD and plug wires and finished it off with platinum performance plugs all were very easy to install, and what a difference in my performance!! I would recommend anyone to do this, all seem to work together nicely ,but the spark plugs made a final touch on starting , and idling like it should. Helped my hole shot greatly. Thanks MYLILPONY

      I see it skips the 86 year does it fit my 5.0 86

      • The NGK G-Power Platinum Performance Spark Plugs do not fit 86 5.0's, we apologize. We do carry the NGK V-Power Performance Spark Plugs, Item 64023 & the NGK Iridium IX Performance Spark Plugs, Item 64009 which are 1986 5.0L specific.

      Will these work with gt40p heads

      • They will work with GT40P heads but you may run into some fitment issues with these spark plugs interfering with the headers.

      Do these spark plugs need to be gaped I bought the mgk g power spark plugs, are they gapped for 95 mustangs or will i need to gap them myself

      • You should ALWAYS check and verify the gap on new plugs. Use a good set of feeler gauges rather than the little circular thing they usually have at the counter at the auto parts store. The proper gap information can be found in your owners manual. If you don't have your owners manual, you can get an electronic version of it at and then look under the support tab.
