Review on 🔌 Autolite APP5364-4PK Dual Platinum Spark Plug, Pack of 4 by Todd Look

Please note these spark plugs must be gapped for use in Mazdaspeed 6 or Mazdaspeed 3. They are packaged as .056. I've replaced them and am ready to install, but first I'm trying another brand, double platinum with two side electrodes as an experiment. These Autolite forks were beautifully packaged in a group of four so they were all in perfect condition but the cardboard tube was missing. Protection of the deal. I doubt they need it because the side electrode is very thick and difficult to bend to repair the break.
