NGK G-Power Spark Plugs -.055 Plug Gap
What GAP to use?
Prior to 2005 GM used .055 GAP (this size) spark plugs on all LSx motors. 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.
This tip is an upgrade over the standard LSx style plugs with better design and performance qualities.
Improved Fuel Efficiency, Lower Emissions, Quicker Starts.
- Fine platinum tip reduces required voltage
- Extremely durable under high heat
- “Trivalent Metal Plating” has superior anti-corrosion and anti-seizing properties
- Faster starts and quicker acceleration
- Better fuel economy and lower emissions
- Best platinum spark plug at an economical cost
Fits most GM LSX (LS1, LS2, LS6, etc) applications. |
