Description
Overview:
This is a Genuine NGK spark plug (CMR5H, NGK 7599), a resistor‐type plug built for dependable ignition in compact petrol engines. It uses a robust steel shell with a high‐temperature ceramic insulator to withstand heat, vibration, and fuel deposits. Designed for Honda mini four‐stroke and compatible small engines, it helps the engine start reliably and run smoothly, supporting clean combustion and steady idle. Ideal for routine servicing of brushcutters, blowers, hedge trimmers, tillers, pumps, and multi‐tool power heads. It is a direct replacement for Honda GX425 and GX435 applications and is sold individually for single‐cylinder engines. Being a Genuine Part from NGK, it meets the correct specification for fit and performance, helping maintain engine efficiency and reduce misfires.
Key Features:
- Genuine NGK part: CMR5H (NGK 7599), specified for Honda small engines
- Resistor design helps suppress electrical interference and protects ignition components
- Reliable cold starting and stable operation under load
- Durable construction for heat, fouling, and vibration resistance
- Consistent combustion supports fuel efficiency and lower emissions
- Easy to fit as a like‐for‐like replacement; check gap to engine specification during service
- Sold individually for convenient maintenance on single‐plug engines
- Suitable for brushcutters, hedge trimmers, blowers, tillers, water pumps, and multi‐tool power units
Typical Applications:
Routine servicing and replacement on Honda mini four‐stroke engines and compatible small engines powering garden and light construction tools. Commonly used on brushcutters/strimmers, hedge trimmers, leaf blowers, compact tillers, water pumps, and modular powerheads used by landscapers, grounds teams, and home users. Fits many machines where Honda GX425 or GX435 engines are specified.
