NGK V-Power TR5 Nickel Spark Plugs for C6 Corvette Base LS3
NGK V-Power TR5 nickel spark plugs, stock number 2238, fit the 2008–2013 C6 Corvette Base with its stock 6.2L LS3 V8. Each order supplies eight spark plugs in two manufacturer four-packs for a complete eight-cylinder spark-plug replacement.
An LS3 spark-plug change is a chance to renew all eight firing points with matching V-Power nickel plugs. The V-groove supports ignition by reducing quenching, while the copper core carries away firing-end heat. Trivalent plating protects the metal shell and allows dry-thread installation. For a stock base C6 used on the road, the result is a straightforward service choice with the material and complete quantity made clear.
Product Details
- Identity: NGK 2238, design code TR5, V-Power nickel spark plugs.
- Firing design: V-groove center electrode with nickel-alloy construction.
- Heat management: 98% pure copper core; high-grade alumina silicate ceramic insulation.
- Shell treatment: Trivalent plating provides corrosion resistance and eliminates the need for anti-seize.
- Package: Eight plugs only. Wires, coils and installation tools are separate.
Benefits
- Ignition support: The V-groove helps improve ignitability while reducing flame quenching.
- Controlled heat flow: The copper core helps dissipate firing-end heat during engine operation.
- Clear service quantity: Two four-packs cover the whole V8, avoiding a half-set order.
- Dry-thread service: The plated shell supports installation without anti-seize, avoiding an unnecessary lubricant that can alter tightening behavior.
Important Notes
- Base-model identity: Select this set for a 2008–2013 base C6 with its stock LS3. Coupe and convertible models are covered; identify the engine rather than relying only on exterior styling or an appearance package.
- Transmission choice: Both the six-speed manual and six-speed automatic are included in this LS3 fitment. The plug quantity remains eight, so order quantity one supplies the complete V8 service set with either transmission.
- Application gap: Use 0.040 inch (1.02 mm) for this stock LS3 fitment. Measure every plug before installation; the supplied preset is not a substitute for the required application setting.
- Installation: Allow the engine to cool before installation. Follow the vehicle’s tightening specification on clean, dry threads without anti-seize. Inspect the ceramic and electrodes for damage, and use the correct spark-plug socket rather than forcing a plug into the cylinder head.
- Modified engines: Have your engine builder confirm the plug specification and gap if compression, boost or other engine requirements have changed.
