NGK Ruthenium HX TR5AHX Spark Plugs for C6 Corvette LS3
NGK Ruthenium HX TR5AHX spark plugs, stock number 94567, fit the 2008–2013 C6 Corvette with the LS3 6.2L engine in stock configuration. This offer includes eight spark plugs supplied as two manufacturer packs of four for a full V8 spark-plug replacement.
Keeping a stock 6.2L LS3 ready for regular drives starts with plugs chosen for the engine in your car. Ruthenium HX pairs a fine ruthenium-alloy center tip with a platinum ground tip. Its double-fine-electrode layout promotes ignitability at the firing end, while durable precious-metal tips help resist wear through repeated ignition cycles in normal street service.
Product Details
- Exact plug identity: NGK 94567, design code TR5AHX, Ruthenium HX.
- Double Fine Electrode design: Fine ruthenium-alloy center and platinum ground firing tips support high ignitability.
- Precious-metal firing surfaces: The ruthenium-alloy center tip provides resistance to wear during repeated sparking.
- Complete V8 quantity: Eight matching plugs in two four-packs; select order quantity one for one engine.
- Included components: Spark plugs only. Plug wires and ignition coils are separate and are not included.
Benefits
- High-ignitability construction: Opposed fine tips help the spark initiate combustion of the air-fuel mixture.
- Wear-resistant firing surface: The ruthenium-alloy center electrode helps resist wear over repeated ignition cycles during regular street use.
- LS3 street maintenance: Give every cylinder a fresh matching plug during routine service on your C6 Base coupe or convertible.
Important Notes
- LS3 model-year coverage: This eight-plug set is for the 2008–2013 C6 Base with the naturally aspirated 6.2L LS3. Verify that engine and year combination rather than choosing by the C6 designation alone.
- Your transmission choice: Both manual and automatic LS3 Base cars use the same TR5AHX set. Coupe and convertible owners receive the same complete eight-plug quantity for a stock-engine refresh.
- Installation gap: Use 0.040 inch (1.02 mm) for this stock LS3 fitment. Measure every plug before installation; do not assume the gap supplied in the box is the required vehicle setting.
- Protect both firing tips: Check with a round-wire or pin gauge. Any adjustment must move only the ground electrode without pressure on the center tip; ask a qualified installer if unsure.
- Installation care: Use clean, dry threads without anti-seize and follow the vehicle tightening specification. Have your engine builder or tuner confirm plug requirements if the engine has been modified.
