Description
Overview:
The NGK BKR5EP-11 Laser Platinum Plug (MPN 3440) is a premium spark plug for petrol engines in cars, vans, and compatible stationary engines. It uses a laser-welded platinum centre electrode with a matching ground pad to deliver a stable spark and long service life. Built around a durable ceramic insulator and a corrosion-resistant steel shell, it is a resistor-type plug to minimise electrical interference with modern engine electronics. Typical fitment details for this plug family include an M14 x 1.25 thread, 19 mm reach (3/4 in), and a 16 mm hex (5/8 in) for standard spark plug sockets. It is supplied pre-gapped to 1.1 mm (approx. 0.044 in), supporting smooth starting, efficient combustion, and reliable performance under everyday driving and varied load conditions.
Key Features:
- Laser-welded platinum centre electrode and ground pad for consistent ignition and extended service life
- Resistor design to reduce radio frequency interference affecting sensors and electronics
- Pre‐gapped to 1.1 mm (approx. 0.044 in) for quick installation and reliable spark
- M14 x 1.25 thread and 19 mm reach (3/4 in) with 16 mm hex (5/8 in) for easy fitting with common tools
- Strong ceramic insulator and robust steel shell for durability under heat and vibration
- Supports smoother idle, easier cold starts, and stable combustion when replacing worn plugs
- Engineered to meet OEM performance standards for fit and function
- Corrosion-resistant plating to help prevent seizing in the cylinder head
Typical Applications:
Used in petrol passenger cars and light commercial vehicles that specify NGK BKR5EP-11. Also suitable for compatible petrol generators and other stationary engines requiring an M14 x 1.25, 19 mm reach, resistor-type platinum plug. Always confirm against the vehicle or equipment manufacturer's specification before installation.
Also known as:
Ignition plug, engine spark plug, petrol spark plug, platinum spark plug, NGK 3440 plug, BKR5EP11 plug, BKR5E platinum plug. These terms refer to the same component used to ignite the air-fuel mixture in petrol engines, supporting efficient running and reliable starts.
