C6 Corvette NGK V-Power Spark Plugs - LS2

NGK V-Power TR5 Nickel Spark Plugs for C6 Corvette Base LS2

NGK V-Power TR5 nickel spark plugs, stock number 2238, fit the 2005–2007 C6 Corvette Base with its stock 6.0L LS2 V8. Each order supplies eight spark plugs in two manufacturer four-packs for a complete eight-cylinder spark-plug replacement.

The early C6’s 6.0L LS2 uses eight plugs, and this set supplies the same nickel V-groove construction for every cylinder. The firing design supports ignitability without relying on a precious-metal tip. Inside, the copper core helps transfer electrode heat; outside, the ceramic insulates the ignition voltage. For routine LS2 maintenance, those features provide a clearly specified plug set that is simple to count and identify before installation.

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

• LS2 identity: This set covers the 2005–2007 base C6 with its stock 6.0L LS2. Coupe and convertible versions share that engine selection, so confirm the installed engine when reviewing the vehicle’s maintenance records.
• Automatic year break: A 2005 automatic has four speeds; 2006–2007 automatics have six. The six-speed manual spans all three years, and both coupe and convertible body styles retain the LS2 selection.
• Application gap: Use 0.040 inch (1.02 mm) for this stock LS2 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.
