The NGK 1100/1200 is a platinum-tipped spark plug featuring a fine wire centre electrode and platinum ground electrode, designed for improved ignition performance, longer service life, and reduced electronic interference compared to standard copper plugs. It is a direct replacement for applications specifying the NGK PMR8B or equivalent.
Key Specifications
- Platinum fine wire centre electrode and platinum ground electrode
- Heat rating: 8
- Thread: M10 × 1.0mm / 19mm reach
- Spanner size: 16mm
- Spark gap: approximately 0.7mm
Key Features
- Platinum tip extends service life significantly over conventional copper plugs
- Fine wire electrode concentrates spark energy for more reliable ignition, especially in hard-starting or lean conditions
- Built-in resistor suppresses radio frequency and electronic interference
- Suitable for motorcycles, scooters, and small-to-medium displacement engines
Installation Note
Always torque to the manufacturer's specification. Under or over-tightening affects heat transfer and can damage cylinder head threads.
Frequently Asked Questions
What plug does this replace? It is a direct replacement for applications calling for the NGK PMR8B or equivalent specification.
How long do platinum plugs last compared to copper? Platinum plugs typically offer significantly longer service life than conventional copper plugs due to the superior wear resistance of the platinum electrode tip.
