B4ES - NGK B4ES Spark Plug
A spark plug produces a high intensity electrical discharge (the spark) inside the combustion chamber, igniting your fuel to keep the engine firing.
It does this thousands of times each minute. Over time spark plugs start to break down, resulting in a poor spark. A healthy engine needs good clean spark plugs.
NGK are the worlds leading spark plug brand, so fit the best.
Suitable for any points type ignition system, our Powerspark Electronic Ignition Electronic Kits, and other electronic ignition systems.
We stock a variety of different spark plugs from NGK, so please check the part number if you are unsure.
This listing is for one plug so if you need more then simply add that number of items to your basket.
Benefits of NGK spark plugs:
- NGK spark plugs use a central electrode with copper deeply inserted in the tip which quickly dissipates large amounts of heat, preventing overheating and fouling
- NGK spark plugs also utilise a trivalent plating, which prevents seizure and acts as a release agent during plug removal. This can act as a lubricant, altering torque values up to 20 percent, so be aware not to over tighten.
