NGK B8EG Racing Spark Plug – Stock No. 3430

The NGK B8EG is a non-resistor racing spark plug designed for reliable ignition under high load and high temperature. It suits tuned engines that run hard, especially performance two-stroke motors. The cold NGK heat range 8 helps control pre-ignition and fouling when the engine is pushed.

It uses a fine-tip nickel centre electrode and a robust ground strap for strong spark energy and stable combustion. This can improve throttle response and consistency at high rpm. Expect smoother running when correctly gapped and matched to your setup.

Note: This is a non-resistor plug. It may cause electrical interference in sensitive ECUs or radios. Use an R-type plug if interference is a concern.

Where it fits

Commonly used in high-performance two-stroke motorcycles, motocross, enduro and kart engines that specify NGK B8EG. Use the vehicle lookup to confirm fitment, or check the Vehicle Fitment tab for full details.

  • Set the gap to your engine’s spec. Too wide can misfire at high rpm, too tight can reduce efficiency.
  • Use a new crush washer and torque correctly for proper heat transfer.
  • Choose the right heat range for your tune and riding conditions to avoid fouling or knock.

The price displayed is for a single plug, please add the desired amount to your basket.

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.
