NGK V-Power TR6 Nickel Spark Plugs for C6 Corvette ZR1 LS9
NGK V-Power TR6 nickel spark plugs, stock number 4177, fit the 2009–2013 C6 Corvette ZR1 with its stock 6.2L LS9 V8. One order includes eight spark plugs in two manufacturer four-packs for a complete eight-cylinder spark-plug replacement during routine scheduled ignition maintenance.
For the factory-supercharged LS9, V-Power provides a V-groove nickel firing surface that supports ignition and reduces flame quenching. The copper core carries heat away from the firing end, and the ceramic insulator isolates the spark’s high voltage. Eight matching TR6 plugs give your stock ZR1 a uniform set for scheduled ignition service, with the engine’s current boost and calibration considered before installation.
Product Details
- Plug identity: NGK 4177, design code TR6, V-Power nickel spark plugs.
- Firing surface: Nickel-alloy center electrode with a V-groove.
- Internal construction: 98% pure copper core and high-grade alumina silicate ceramic insulation.
- Shell finish: Trivalent plating provides corrosion resistance and supports dry-thread installation.
- Included parts: Eight matching plugs only. Plug wires, ignition coils and installation tools are separate.
Benefits
- Ignitability: The V-groove helps the spark start the air-fuel burn with less flame quenching.
- Heat control: The copper core transfers heat away from the firing end during operation.
- Electrical insulation: The ceramic separates the high-voltage spark path from the metal shell.
- Whole-engine service: Replace all eight plugs together with a matching nickel design and one complete order.
Important Notes
- Factory boost: The 2009–2013 ZR1’s original supercharged 6.2L LS9 is included in this fitment. Its coupe body, dry-sump lubrication and six-speed manual identify the factory configuration.
- Changed calibration: If a pulley, boost target, fuel system or tune has changed, have your tuner confirm the plug choice and gap. Match those recommendations to the engine’s current setup before starting an ignition refresh.
- Installation gap: Use 0.040 inch (1.02 mm) for the stock LS9. Measure each plug before fitting it; the supplied preset does not replace an individual gap check.
- Dry-thread fitting: Do not add anti-seize. Follow the vehicle’s tightening specification so the plug seats correctly and can transfer heat through the cylinder head.
- Service preparation: Keep dirt out of the spark-plug openings. Let the engine cool, inspect the ceramic and electrodes for damage, and start each plug carefully by hand. Check wire boots for deterioration and confirm they are securely seated when the job is finished.
