NGK G-Power TR5GP Platinum Spark Plugs for C5 Corvette Z06 LS6
NGK G-Power TR5GP platinum spark plugs, stock number 3186, fit the 2001–2004 C5 Corvette Z06 LS6 with its stock LS6 5.7L V8. This offer supplies eight spark plugs as two manufacturer packs of four, giving you a complete engine set for scheduled spark-plug replacement.
G-Power gives your stock LS6 a single-platinum firing tip with a 0.6 mm fine-wire center electrode. The fine tip supports ignitability, and the trapezoidal ground electrode limits the cooling effect that can interrupt the developing flame. Together, those details make this a straightforward precious-metal option for a Z06 ignition refresh.

Important Notes
- Z06 model selection: This set covers the 2001–2004 C5 Z06 with the original-specification 5.7L LS6. Check the LS6 engine identity together with the Z06 model year before choosing your replacement plugs.
- Manual-transmission coupe: C5 Z06 coverage is the fixed-roof coupe with its manual transmission. When servicing this older Z06, inspect the plug-wire boots and keep their routing clear of hot exhaust components.
- Application gap: Use 0.040 inch (1.02 mm) for this stock LS6 fitment. Check each plug before fitting it; the factory setting is not assumed to match the required engine gap.
- Fine-wire care: Measure with a round-wire or pin gauge. If adjustment is needed, move only the ground electrode without levering against the platinum center tip or ceramic insulator.
- Installation: Fit clean, dry threads without anti-seize and follow the vehicle torque specification. Have your engine builder confirm requirements for a modified engine before ordering.
