NGK G-Power TR6GP Platinum Spark Plugs for C6 Corvette Z06
NGK G-Power TR6GP platinum spark plugs, stock number 5141, fit the 2006–2013 C6 Corvette Z06 with its stock LS7 7.0L naturally aspirated V8. This offer includes eight spark plugs supplied as two manufacturer packs of four, enough for a complete V8 spark-plug replacement.
G-Power supplies a 0.6 mm fine-wire platinum center electrode for focused sparking, paired with a trapezoidal ground electrode that reduces flame quenching. For a naturally aspirated LS7 ignition refresh, that gives you a consistent single-platinum design across all eight cylinders. The copper core carries heat away from the firing end during normal engine operation.
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
- Z06 ordering check: Match the 2006–2013 model year, Z06 coupe and 7.0L LS7 together. The coupe body and six-speed manual transmission belong to this factory configuration; the engine identity is the key plug-selection detail.
- Service planning: Keep the TR6GP stock number with your Z06 maintenance records. If its engine has been rebuilt or modified, confirm its current plug requirements instead of relying only on the original model badge.
- Application gap: Use 0.040 inch (1.02 mm) for this stock LS7 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.
