NGK B5ES Spark Plug – Stock No. 6410
The NGK B5ES is a standard nickel-alloy spark plug with a copper core. It delivers reliable ignition, steady idle and clean combustion in many classic and small-capacity engines. It is a non-resistor type, suited to simple ignition systems and older vehicles.
Use it when you want consistent starting, smooth running and long service life without fuss.
- Stable spark for easy starts and smooth idle
- Copper core for better heat transfer and durability
- Standard, non-projected tip to suit many classic applications
- Non-resistor design for maximum spark energy
If your vehicle has sensitive electronics or you use on-board comms/audio, consider a resistor plug (e.g. NGK R types) to reduce radio interference.

In the words of the Vehicle Standards Agency (VCA), type approval provides "confirmation that production and samples of a design will meet specified performance standards".
For emissions components this encompasses noise, emissions and balanced back pressure, which have a strong influence on maintaining engine performance (power), and fuel efficiency. Type approval ensures that an aftermarket component will reach, or exceed the performance standard of the corresponding OE part.
Type-approval then, is a certain guarantee that an end user will receive a product of OE equivalent performance attributes.
Products on the Progressive Parts website that meet this approval will be clearly marked or labelled EC or ECE approved.
