Description
Overview:
The NGK PTR6F-13 Spark Plug (MPN 7569) is a genuine ignition component for petrol engines used across garden machinery and construction equipment. Built with a robust steel shell and a durable glazed ceramic insulator, it delivers a reliable spark to ignite the air-fuel mixture for easy starting and smooth running. The "R" in the code denotes an internal resistor to reduce electrical interference, while the "-13" suffix indicates a factory-set gap of 1.3 mm (0.052 in). Heat range "6" on the NGK scale suits many engines that specify a medium heat plug. Fit this plug as a like-for-like replacement where PTR6F-13 is listed by the manufacturer. It's a dependable choice for tradespeople and DIY users who want consistent performance from their equipment.
Key Features:
- Genuine NGK part (MPN 7569) for assured compatibility and performance
- Resistor type ("R") suppresses electromagnetic interference for stable operation
- Factory-set gap 1.3 mm (0.052 in) as denoted by "-13"
- Medium heat range 6 helps balance fouling resistance and heat dissipation
- Tough metal shell and high-grade ceramic insulator for long service life
- Precision tolerances for consistent spark, smooth idle, and reliable restarts
- Corrosion-resistant plated shell helps prevent seizing in the cylinder head
- Sealed construction helps keep contaminants away from the insulator nose
- Straightforward to fit with a suitable spark plug socket and basic tools
- Suitable where PTR6F-13 is specified on garden and light construction machinery
Typical Applications:
Used on petrol-powered equipment that specifies NGK PTR6F-13, including lawn mowers, generators, compactors/plate wackers, cut-off saws, pressure washers, brush cutters, and small pumps. Ideal for plant hire fleets and home workshops needing reliable starts and steady running. Always confirm the plug code and gap with the machine's handbook before installation.
Also known as:
Spark plug, ignition plug, engine spark plug, spark igniter, combustion igniter, NGK 7569, PTR6F13 (no dash), resistor spark plug. These terms refer to the same type of plug used to ignite the air-fuel mixture in petrol engines where this specific NGK code is required.
