NGK Iridium IX Spark Plugs -.055 Plug Gap
What GAP to use?
Prior to 2005 GM used .055 GAP spark plugs on all LSx motors (this size). Starting in 2005, they switched to .040 GAP plugs to provide a better idle when things like cheap gas are encountered. Either a .060, or .040 GAP plug will work in any LSX motor with the smaller GAP being best for daily driven, mildly modded cars.
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 Fits most GM LSX (LS1, LS2, LS6, etc) applications.
