    • Autolite Spark Plug Features

      There are a wide variety of spark plugs available for many different engine configurations and types – everything from small engine spark plugs for lawn mowers, to high-performance plugs for racing applications.


      While the Autolite spark plug line-up may vary in different world markets, the North American Autolite line-up includes:


      • Copper Core
      • Platinum
      • Double Platinum
      • Iridium XP Enhanced Alloy Technology™
      • Racing Hi-Performance
      • Revolution HT

      Iridium XP Enhanced Alloy Technology™

      One of the brand’s most technologically advanced spark plugs ever. With an iridium enhanced 0.6 mm fine wire design and patented platinum sidewire technology, these spark plugs provide better durability** and a more focused ignition for optimum performance.


      • Better overall ignitability*
      • Greater overall durability**
      • Better overall value

      *Compared tostandard plugs, multi-electrode design plugs and even 0.8 mm fine wire plugs! **Compared to average of other premium brands

      Double Platinum

      Feature platinum-to-platinum firing. Virtually eliminates gap erosion, reduces misfires and provides 100,000-mile durability. It’s a superior performance spark plug providing preferred technology for distributorless ignition engines.


      • Superior performance
      • Longer life compared to standard plugs
      • Improved efficiency over the life of the plug compared to worn plug

      Platinum


      Manufactured with a center wire platinum firing tip. Benefits include: Reduced gap erosion, fewer misfires, better performance and more durability that the standard plug.


      • Longer life
      • Quick starts
      • Faster acceleration
      • Fewer misfires
      • Cleaner firing and improved efficiency over the life of the plug compared to worn plug

      Copper

      Guaranteed to deliver quick starts, dependable performance and smooth acceleration. Autolite® Copper Core plugs are the industry standard.


      • Super heat dissipation and durability
      • Improved fuel economy
      • Smooth acceleration
      • Lower emissions

      Revolution HT

      Unique, patented design improved for greater durability. High-Strength Steel (HSS) Technology helps prevent separation of shell and ground shield.


      • Patented Autolite technology
      • Exclusively designed for Ford Motor Company’s Triton three-valve engines
      • Four heat ranges available: HT1, HT1.5, HT2 and HT0 for modified engines

      Racing Hi-Performance

      Actual racing spark plug used by many professional car drivers. Anti-corrosive nickel plating and large, cut-back ground electrode for better heat transfer.


      • Cut back ground electrode for improved ignitability
      • Anti-corrosive nickel Plating
      • Large ground electrode for better heat transfer

    • Iridium XP Enhanced Alloy Technology™



      • Iridium-enhanced center electrode
      • Patented, platinum sidewire technology
      • 0.6-mm finewire design
      • Nickel-plated shell

      Double Platinum



      • High nickel alloy side electrode
      • Full platinum tips
      • Necked-down center electrode
      • Full copper core center electrode

      Platinum


      • High nickel alloy side electrode maintains precise gap
      • Full platinum tip assures virtually no gap erosion
      • Necked-down center electrode fires quicker, cleaner with
        less voltage for easier starts, quicker acceleration and improved fuel economy*

      *As compared to standard plugs

      Copper

      • Copper-glass seal bonds insulator, terminal post center electrode together; assures full
        required voltage at spark gap; gas-tight seal (100% leak proof)
      • Multi-rib insulator reduces danger of "flash-over"
      • One-piece terminal post adds strength
      • Resistor reduces radio frequency interference (RFI) and electrode erosion
      • Cold-formed steel shell precision rolled threads

      Revolution HT® High Thread

      • Insulator - High alumina ceramic body
      • Spark Plug Assembly - Jam nut is "hot-pressed" onto the insulator/ground shield
      • Motor Seat - Contact area for sealing to engine cylinder head
      • Platinum alloy enhancement in "fine-wire" form on center electrode
      • Terminal Stud - Uses SAE1008 steel with nickel-plated finish
      • Jam Nut - 9/16" hex with 16 x 1.5-mm thread, nickel-plated steel
      • Resistor Seal - Conducting glass-seal terminations and carbon-based resistor
      • Copper-Core Center Electrode - Made with nickel-alloy sheath over a copper core (2.16-mm diameter)

      Racing® Hi-Performance

      • Yttrium-Enhanced Alloy enables up to 8% reduction in sidewire temperature for
        colder heat ranges designed to enable performance modifications and handle intense conditions.*
      • Cut back ground electrode for better ignitability of the flame kernel
      • Anti-corrosive nickel plating to prevent rusting better than black oxide
