NGK G-Power TR6GP Platinum Spark Plugs for C6 Corvette ZR1
NGK G-Power TR6GP platinum spark plugs, stock number 5141, fit the 2009–2013 C6 Corvette ZR1 with its stock LS9 6.2L supercharged V8. This offer includes eight spark plugs supplied as two manufacturer packs of four, enough for a complete V8 spark-plug replacement.
The ZR1 starts with a factory-supercharged LS9, so plug selection should begin with that engine configuration. G-Power combines a 0.6 mm platinum center tip with a trapezoidal ground electrode for focused sparking and reduced flame quenching. Eight matching plugs provide a consistent single-platinum design for routine stock-engine service, while the copper core helps carry heat away from the firing end.
Product Details
- Plug identity: NGK 5141, design code TR6GP, G-Power platinum spark plugs.
- Firing-end construction: Single platinum center tip, 0.6 mm fine-wire center electrode and trapezoidal ground electrode.
- Internal materials: 98% pure copper core with high-grade alumina silicate ceramic insulation.
- Quantity: One order supplies eight matching plugs in two four-packs.
- Included: Spark plugs only; plug wires, ignition coils and installation tools are separate.
Benefits
- Focused sparking: The fine platinum tip supports ignitability during combustion.
- Less flame quenching: The shaped ground electrode helps limit interference with the developing flame.
- Heat dissipation: A copper core helps carry firing-end heat away, while the ceramic provides electrical insulation.
- Complete service quantity: Replace all eight plugs together without calculating how many four-packs your V8 needs.
Important Notes
- Stock boost scope: The 2009–2013 ZR1’s original LS9 supercharger is included in this fitment. Match the LS9 engine code, model year and ZR1 coupe when selecting your service set.
- Modified ZR1 check: If boost, calibration or internal engine specification has changed, have your tuner confirm the plug and gap before ordering. A factory-supercharged fitment is not a blanket recommendation for every higher-boost setup.
- Application gap: Use 0.040 inch (1.02 mm) for this stock LS9 fitment. Measure every plug before installation; its supplied preset is not assumed to equal the required engine setting.
- Fine-wire care: Use a round-wire or pin gauge. Adjust only the ground electrode without levering against the platinum center tip or ceramic.
- Installation: Use clean, dry threads without anti-seize and follow the vehicle’s tightening specification. Allow the engine to cool before starting the service. Inspect the ceramic and electrodes for damage, and confirm each wire boot is securely seated afterward.
