Spark plugs play a vital role in producing the maximum power from an engine whilst keeping fuel consumption and emissions to a minimum.

Copper’s superior heat conductivity dissipates the heat of combustion away from the firing end, preventing hot spots that can lead to pre-ignition. of an engine including physical dimensions; combustion chamber shape; cooling abilities; fuel and ignition systems. NGK is the brand leader in the UK spark plug market and are the world's biggest supplier to many major car manufacturers. Eliminate "flashover", which can cause misfiring and engine damage, especially in damp environments.Some engines require the use of two spark plugs per cylinder and again due to space restrictions these might be of different sizes. Compared to ordinary plugs with equal anti-fouling resistance; NGK Spark Plugs have a higher pre-ignition rating. Choosing the correct spark plug type will help a vehicle manufacturer meet legislated emission targets and assists the motorist in getting the best from their engine. NGK is the leader in Motorcycle Spark Plugs, with spark plugs for virtually every Motorcycle, ATV, and Scooter application in the world. To combat the ‘cold fouling’ effect that can occur in some engines using unleaded fuels specially arranged ground electrodes are sometimes used.

The spark plug insulators are made of 99 percent pure alumina silicate, allowing for longer insulator noses for reduced fouling. Copper wire used in place of the iron core in conventional plugs is the secret of NGKs Wide Heat Range. NGK has the technology to produce plugs for every type of automotive engine, as well as for motorcycles, marine, horticultural and many other applications. A wide range spark plug is more flexible and performs equally well in a hot or cold engine under stop and go city driving or fast motorway cruising. A change in spark plug design; possibly the adoption of a taper seat and extended reach (threaded portion) or even the use of a smaller diameter is often the answer.NGK the number 1 for spark plugs, This is the workhorse, the plug that is at the heart of smooth-running engines around the world. NGK Spark Plugs are specified by more motorcycle manufacturers, including Honda, Yamaha, Suzuki, and Kawasaki.

Oily deposits start to build up after this sort of mileage and can cause starting problems and a drop in performance.

Copper cored electrodes also mean that longer insulator noses can be used to protect against fouling. Every year the range of NGK spark plugs grows to accommodate the ever increasing demands of modern engines.NGK employ the very latest production technology to ensure that every aspect is catered for – performance; economy and value.
