NGK G-Power LTR5GP Platinum Spark Plugs for C7 Corvette Z06
NGK G-Power LTR5GP platinum spark plugs, stock number 5019, fit the 2015–2019 C7 Corvette Z06 with its stock LT4 6.2L supercharged V8. Each order includes eight spark plugs supplied as two manufacturer four-packs, providing a complete set for V8 spark-plug replacement.
For the Z06’s factory-supercharged LT4, pay attention to both plug identity and the installation gap. G-Power uses a 0.6 mm platinum center electrode and a shaped ground electrode for focused sparking and reduced flame quenching. Eight matching plugs support routine service of the original engine configuration, with the required gap checked individually before installation.
Product Details
- Product identity: NGK 5019, design code LTR5GP, G-Power platinum spark plugs.
- Center electrode: Single platinum tip with a 0.6 mm fine-wire design.
- Supporting construction: Trapezoidal ground electrode, 98% pure copper core and high-grade alumina silicate ceramic insulation.
- Service quantity: Eight matching plugs; two four-packs supplied per order.
- Included components: Spark plugs only. Ignition coils, plug wires and installation tools are separate.
Benefits
- Focused ignition: The fine platinum tip supports ignitability with a concentrated spark.
- Less flame quenching: The ground-electrode shape limits interference with the developing flame.
- Thermal management: The copper core helps dissipate firing-end heat; the ceramic electrically insulates the plug.
- One complete service order: The eight-plug quantity avoids accidentally buying only half the set your Corvette needs.
Important Notes
- Factory-supercharged fitment: Match the 2015–2019 Z06, its 6.2L LT4 and stock engine configuration. Coupe and convertible models are covered with either factory transmission choice.
- Modified boost: A smaller supercharger pulley, altered calibration or internal engine changes can affect plug requirements. Have your tuner confirm the plug specification and gap for the current setup before fitting a stock-engine service set.
- Application gap: Use 0.032 inch (0.81 mm) for this stock LT4 fitment. Measure every plug before installation; do not assume its supplied preset matches the required setting.
- Fine-wire care: Check with a round-wire or pin gauge. Move only the ground electrode when adjusting; never lever against the platinum tip or ceramic. If the required change exceeds 0.008 inch from the supplied gap, consult NGK before proceeding.
- Installation: Allow the engine to cool before installation. Follow the vehicle’s tightening specification on clean, dry threads without anti-seize. Inspect each plug for damage and check that the wire boots are securely seated after installation.
