The NGK LKAR8A-9 spark plug is a proven choice for motocross and enduro when you need a reliable start, smooth engine operation, and consistent performance. It helps maintain proper combustion even under heavy loads and is ideal as a replacement during servicing or as a spare for races.
Benefits
reliable starts, both cold and warm
stable performance and smooth engine operation
suitable for demanding off-road conditions
ideal as a quick replacement in the pits or for races
Basic Specifications
Socket size: 14 mm
External thread: M12 x 1.25 mm
Thread length: 26.5 mm
Spark gap: 3.0 mm
Spark Plug Design
Center electrode: nickel
Outer electrode: standard design
Resistance: 5 kOhm
NGK Design Advantages (for longer service life)
Standard NGK spark plugs are designed for long service life and optimal performance even under load.
Triple-metal plating for excellent anti-corrosion and anti-adhesion properties
Corrugated insulator ribs prevent spark leakage
Aluminosilicate ceramic insulator for higher strength and better heat transfer
Copper core for efficient heat dissipation
Triple seal for protection against leakage
How to read NGK markings (letters and numbers)
The combination of letters and numbers on each NGK spark plug is not just a type designation, but a standardized code that precisely defines the spark plug’s design and properties. This makes it easier to select the correct spark plug for the engine (for original equipment manufacturers, service providers, workshops, and customers).
Meaning of the positions in the marking
Positions 1–4 (letters): thread diameter, wrench size, and design type
Position 5 (number): heat range
Position 6 (letter): thread length
Position 7 (letter): special design features
Position 8 (number): electrode gap (coded)
