NGK 5141 G-Power Platinum Spark Plug, Heat Range 6, 14mm Thread, Tapered Seat

The NGK 5141 G-Power Platinum spark plug is a single platinum, resistor-type spark plug. It is built as a step up from conventional nickel alloy plugs. NGK is a leading original equipment spark plug supplier, and G-Power Platinum gives you platinum durability at a moderate price.

Key Features:

• Single platinum tip: The fine wire platinum center electrode (0.6 mm) gives a stable spark and good durability.
• Solid copper core: The 98% pure copper core improves heat dissipation and conductivity, and it supports a wide heat range.
• Trapezoidal cut ground electrode: The design reduces quenching, which improves ignitability and performance.
• Cold-rolled threads: They help prevent cross-threading and damage to the cylinder head.
• Built-in resistor: The 5,000 ohm resistor helps suppress radio frequency interference.
