NGK Ruthenium HX TR6AHX Spark Plugs for C6 Corvette Z06 LS7
NGK Ruthenium HX TR6AHX spark plugs, stock number 92714, fit the 2006–2013 C6 Corvette Z06 with the stock LS7 7.0L V8. This offer supplies eight spark plugs as two manufacturer packs of four for a complete spark-plug replacement and regular street maintenance.
The Z06’s naturally aspirated 7.0L LS7 combines eight cylinders with a manual-transmission coupe layout. For a stock-engine ignition refresh, Ruthenium HX uses a fine ruthenium-alloy center tip facing a platinum ground tip. This Double Fine Electrode construction supports high ignitability, while the precious-metal firing surfaces resist wear through repeated ignition cycles on your regular drives.
Product Details
- Exact product: NGK 92714, design code TR6AHX, Ruthenium HX.
- Double Fine Electrode design: A fine ruthenium-alloy center firing tip works opposite a fine platinum ground tip.
- Precious-metal construction: The firing-tip materials combine high ignitability with resistance to electrode wear.
- Complete V8 quantity: Eight matching plugs in two four-packs; order quantity one supplies one engine.
- Package contents: Spark plugs only. Ignition wires and coils are separate components and are not included.
Benefits
- High-ignitability firing end: The DFE arrangement helps the spark initiate combustion of the air-fuel mixture.
- Wear-resistant firing tips: Precious-metal electrode surfaces help maintain the firing end through repeated sparking during normal street service.
- Full Z06 plug refresh: Renew all eight cylinders together when maintaining the stock LS7 in your manual-transmission coupe.
Important Notes
- Z06 year range: Match the 2006–2013 model years to the original-specification LS7 7.0L engine. The first 2006 Z06 and final 2013 Z06 use the same TR6AHX plug selection for this stock application.
- Coupe service planning: This Z06 fitment covers the coupe with its six-speed manual transmission. Use the LS7 vehicle service procedure when accessing the plugs, and inspect the existing plug-wire boots as part of the service.
- Installation gap: Use 0.040 inch (1.02 mm) for this stock LS7 fitment. Measure every plug before installation; the supplied preset is not a substitute for the vehicle-specific setting.
- Protect the firing tips: Use a round-wire or pin gauge to check the gap. Any adjustment must move only the ground electrode without pressure on the center tip or ceramic insulator.
- Dry-thread installation: Install these NGK plugs without anti-seize or lubricant on the threads. Added lubricant changes the tightening conditions, so keep the threads dry and use the vehicle’s specified installation procedure.
- Inspect before fitting: Check each replacement plug for handling damage before installation. If a plug has been dropped or its fine firing tips appear damaged, have it checked before use.
- Modified engines: Have your engine builder or tuner confirm spark-plug requirements if your LS7 has been modified.
