Product Information
Full details
The NGK BKR6EZB (4293) spark plug is designed for automotive enthusiasts and DIY mechanics seeking reliable combustion performance in petrol engines. This component is essential for igniting the air-fuel mixture to generate engine power, offering a high-quality nickel centre electrode for consistent reliability. While it provides excellent compatibility across a range of vehicles, users must verify that the 19mm thread length and 14mm thread diameter strictly match their specific engine manufacturer specifications before installation.

FAQs
What is the hex size for this plug?
The NGK 4293 requires a 16mm spark plug socket.
Does this spark plug come pre-gapped?
While these plugs are often set to a general factory gap, you should always check and adjust the gap to match your specific vehicle manufacturer's specifications before installation.
What does the 1kOhm rating signify?
The 1kOhm rating indicates the internal resistor value, which helps suppress electromagnetic interference (EMI) that could affect your vehicle's radio or engine management systems.
How often should I replace these plugs?
Refer to your vehicle's maintenance schedule; typically, standard nickel plugs are replaced every 20,000 to 40,000 miles depending on driving habits.
Can I use this in a high-performance racing engine?
The BKR6EZB is a standard-grade plug. High-performance or forced-induction engines may require plugs with higher heat ratings or precious metal electrodes (Iridium/Platinum).
Troubleshooting
Engine misfire after installation
Verify the spark plug gap is set to the manufacturer's specified clearance and ensure the ignition wire is seated firmly on the terminal.
Plug appears carbon-fouled
Check for rich fuel mixtures, faulty oxygen sensors, or excessive idling, as these can cause soot buildup on the electrode.
Difficulty threading into the engine
Do not force the plug; remove it and check for damaged threads on the cylinder head or cross-threading during the initial start.
Pros and Cons
Pros
- High-quality manufacturing standards from a trusted brand
- Effective radio frequency interference suppression
- Consistent spark performance
- Standardized dimensions for ease of installation
Cons
- Requires precise torque specifications to avoid damage
- Not suitable for engines requiring iridium or platinum performance variants
- Must be gapped correctly for specific vehicle requirements
Setup, Compatibility & Care
Proper installation is critical to the longevity of the NGK 4293. Before installing, ensure the threads in the cylinder head are clean and free of debris. Always use a torque wrench to tighten the plug according to the vehicle manufacturer’s service manual, as over-tightening can crack the ceramic body or damage the threads.
- Compatibility: Always cross-reference the `BKR6EZB` part number with your vehicle’s owner manual or manufacturer parts catalog.
- Handling: Handle the plugs by the metal body rather than the ceramic tip to avoid microscopic fractures.
- Inspection: During regular maintenance, check the electrode for signs of excessive wear or carbon buildup, which may indicate a need for fuel system adjustment or ignition timing checks.
