NGK B-4H Spark Plug – Stock No. 4110

A reliable, standard nickel spark plug for classic engines and small-capacity applications. It helps maintain smooth starting, stable idle, and clean combustion. Good for everyday use and light performance tuning where a hotter heat range is required.

  • Hotter NGK heat range 4 – helps resist fouling in short trips and low-load running
  • Short-reach 14 mm plug for many older engines and small equipment
  • Non-resistor type – ideal where the ignition system specifies no resistor

What it does and why it matters

The spark plug ignites the air-fuel mix. Correct reach, heat range, and gap improve starting, throttle response, and plug life. The B-4H uses a durable nickel centre electrode and a standard ground strap for consistent performance under normal road use.

Check your handbook or use the site’s vehicle lookup to confirm fitment, heat range, and reach before ordering.

What do our stock statuses mean?

1+ IN STOCK in green stock is readily available in one of our warehouses for express delivery (at the time of viewing).

LOW STOCK in green means we're running low! 1 or 2 left on the shelf so act fast. Over evenings, weekends and bank holidays this stock can move quickly so please bear this in mind.

0 IN STOCK in blue means our primary warehouse does not have unallocated stock, but our UK partners do. Often these can be shipped quickly and efficiently. You'll be notified via the Track My Order page if further delays are unavoidable.

Thank you, Team PP

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.
