    Autolite XP Xtreme Performance spark plugs

     

    Introducing the new Autolite XP Xtreme Performance Spark Plugs. With an iridium-enhanced, .6 mm finewire design and patented platinum sidewire technology, these plugs provide more focused ignition for better overall ignitability and improved durability.

    Independent lab tests prove that Autolite XP Xtreme™ Performance Spark Plugs provide better overall ignitability and durability than many other premium spark plugs.  By increasing the size of the flame kernel, you get a 21 percent bigger flame compared to that of standard plugs.  The new Autolite plugs ignite more gas and air mixture inside the cylinders to deliver better overall performance. The ignition is also more focused, which provides better and faster fuel combustion, optimizing the vehicles spark plug performance.

    I replaced mine and left the stock gap (.050) This ran fine on the stock tune, when I upgraded to GMS1 it caused a misfire at higher rpm's. I regapped to the LNF stock gap (.034) which caused horrible drivability issues. I called Autolite support and they gave me the propper gap for these plugs in the LNF, which is .043-.045. Have put well over 22,000 miles on them so far with zero issues.
    Good OEM replacement plug

    Got these to troubleshoot P030x code on my cobalt SS/TC. Fixed the problem, the car seems to pull harder. Need to make sure the gap is set correctly first, since they come pre-set to .050 from the manufacturer, and the LNF engine should have them set at .032-.035
