NGK Iridium IX Spark Plugs -.040 Plug Gap

What GAP to use?

Prior to 2005 GM used .055 GAP spark plugs on all LSx motors. Starting in 2005, they switched to .040 GAP (this size) plugs to provide a better idle when things like cheap gas are encountered. Any LS2, LS3, L99, or LS7 will come from the factory with a .040 GAP

Best replacement plug for stock/midly modified LSx motors.

The Spark Plug Serious Enthusiasts Rely On

Designed specifically for the performance enthusiast.  Iridium IX offers extreme ignitability, improved throttle response and superior anti fouling

  • Fine Iridium tip ensures high durability and a consistently stable spark
  • Iridium alloy has extremely high melting point, perfect for today’s high-tech, high-performance engines
  • “Trivalent Metal Plating” has superior anti-corrosion and anti-seizing properties
  • Outstanding acceleration, high fuel efficiency and durability
  • Ultimate design, technology and performance

Fits most GM LSX (LS1, LS2, LS6, etc) applications.
