NGK V-Power TR5 Nickel Spark Plugs for C5 Corvette Z06 LS6
NGK V-Power TR5 nickel spark plugs, stock number 2238, fit the 2001–2004 C5 Corvette Z06 with its stock 5.7L LS6 V8. Each order supplies eight spark plugs in two manufacturer four-packs for a complete eight-cylinder spark-plug replacement.
For a stock LS6 ignition refresh, V-Power’s nickel V-groove supports ignitability and helps reduce quenching around the firing electrodes. Its copper core handles heat transfer, and the ceramic provides electrical insulation. Eight matching TR5 plugs let you renew the full Z06 set together, while the plated shells are designed for installation without added anti-seize. That keeps the service centered on the plugs your engine needs.
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
- Original Z06 configuration: Match the 2001–2004 model years, 5.7L LS6, fixed-roof coupe body and six-speed manual transmission. These details identify the stock C5 Z06 covered by this complete eight-plug set.
- Maintenance records: Record the installed plug number and checked gap when servicing your LS6. Nickel plugs should be maintained for their own construction and use; do not assume an unverified replacement interval from a previously installed plug type.
- Application gap: Use 0.040 inch (1.02 mm) for this stock LS6 fitment. Measure every plug before installation; the supplied preset is not a substitute for the required application setting. Work on a cool engine and keep dirt out of the plug openings.
- 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.
