NGK Iridium IX TR5IX Spark Plugs for C6 Corvette LS2
NGK Iridium IX TR5IX spark plugs, stock number 7397, fit the 2005–2007 C6 Corvette with the LS2 6.0L engine in stock configuration. This offer includes eight spark plugs supplied as two packs of four for a complete V8 plug service.
An early C6 plug change starts with the 6.0L LS2 actually fitted to your car. Iridium IX uses a fine iridium firing tip to support a stable spark and resist electrode wear. A plated shell helps protect the threads during service, while the complete eight-plug quantity lets you replace the full set together for regular driving and weekend trips.
Product Details
- NGK stock number: 7397; design code: TR5IX.
- Fine-wire iridium center electrode: A durable firing tip designed to maintain a consistent spark.
- Full eight-plug quantity: Two manufacturer packs of four for one V8 engine.
- Spark plugs only: Plug wires and ignition coils are separate components and are not included.
- Trivalent shell plating: Helps resist corrosion and supports removal at a later plug service.
Benefits
- A matching set: Replace all eight plugs with the same Iridium IX design in one order.
- Wear-resistant firing tip: Iridium supports stable ignition while resisting electrode wear.
- Focused early-C6 fitment: Select an eight-plug service set for the 2005–2007 LS2 coupe or convertible.
Important Notes
- Early C6 selection: Match the 2005–2007 model year and 6.0L LS2 engine together. That combination identifies the stock-engine fitment for this eight-plug service set.
- Coupe or convertible: Both body styles use this eight-plug offer when equipped with the stock LS2. Choose by the engine and year rather than the roof style.
- Check before fitting: Confirm TR5IX and 7397 on the plugs and packaging, then inspect the ceramic insulators and electrodes for damage.
- Installation gap: Use 0.040 inch for this stock LS2 fitment. Measure every plug before installation; the supplied gap is not a substitute for the vehicle’s required setting.
- Protect the fine tip: Use a round-wire or pin gauge. Move only the ground electrode if adjustment is needed, without levering against the center tip. Ask a qualified installer before making a large adjustment.
- Dry threads and correct torque: Do not add anti-seize or lubricant. Follow the vehicle tightening specification. An engine builder or tuner should confirm plug requirements for a modified engine.
