NGK G-Power LTR5GP Platinum Spark Plugs for C7 Corvette Stingray
NGK G-Power LTR5GP platinum spark plugs, stock number 5019, fit the 2014–2019 C7 Corvette Stingray with its stock LT1 6.2L naturally aspirated V8. Each order includes eight spark plugs supplied as two manufacturer four-packs, providing a complete set for V8 spark-plug replacement.
Give your Stingray’s ignition service a consistent starting point with a single-platinum firing design across all eight cylinders. G-Power pairs a fine platinum center tip with a shaped ground electrode to concentrate the spark and reduce flame quenching. The construction suits a straightforward stock-LT1 maintenance choice, whether your Corvette is a coupe or convertible.
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
- Model-year check: A 2014 Stingray may have a six-speed automatic; 2015–2019 automatics use eight speeds. The seven-speed manual spans this range. All retain the LT1 identity used to select this plug set.
- Service records: Match your Stingray’s present engine to the original LT1 specification. An engine swap or added forced induction calls for a fresh plug recommendation from the builder, rather than selection by the Stingray badge alone.
- Application gap: Use 0.040 inch (1.02 mm) for this stock LT1 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: 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.
