Turn to DENSO Spark Plugs this riding season
Although spark plugs are extremely durable, the entire time the machine is running, the electrodes across which the spark jumps to ignite the fuel to power the engine, are being eroded. Although the amount of damage made by each spark may be too small to measure, each plug could easily spark more than 200,000 times during just a two hour ride, and when it gets to this kind of level, that begins to make a difference.
As the spark plugs gradually wear, their performance slowly begins to drop. This is generally not noticeable during the course of a normal riding season, but fitting a new set in the spring can make a tangible difference in terms of both the engine’s power and response, as well as its fuel efficiency.
DENSO is a leading spark plug designer and manufacturer, supplying original equipment (OE) plugs to both motorcycle and car manufacturers globally. As a result, in its broad aftermarket range, it has an appropriate, OE quality spark plug for almost every application, which allows riders to select a like for like replacement and restore lost ignition performance.
The story doesn’t end there however, as often there are additional performance gains to be made by upgrading the OE specification spark plugs with a set that is of a different design or uses alternative technology. Not only can this increase the aforementioned engine power and responsiveness, but it can also reduce emissions and subsequently bring a machine of an older design up to current emissions standards, for example.
DENSO’s patented twin tip (TT) spark plugs achieve these gains by using thinner electrodes made from more durable materials, such as platinum or iridium. These thinner electrodes produce a more concentrated spark, which is more powerful and consistent across its 360-degree circumference, and maximises the engine’s combustion efficiency.
These factors increase power, while reducing exhaust emissions and improving fuel consumption, as well as requiring less energy from the ignition coil. In addition, the use of these hardwearing materials means that DENSO Iridium TT spark plugs deliver a much longer service life, sometimes up to 120,000km, which also makes them a cost-effective replacement solution, whatever the time of year!
Product Selection
When sourcing the correct replacement spark plug, it is important to clearly identify the model and engine code, its emission standard, production year and engine power output rating. Also, be aware that machines sold in different regions sometimes specify a different spark plug type.
Although crucial for the vehicle manufacturers, some detailed specifications may be less relevant for the aftermarket, which is why purely aftermarket suppliers often apply a consolidation logic to make their range more efficient. However, the skill of judging consolidation alongside quality standards varies greatly between each supplier. Therefore, it is highly recommended to only purchase spark plugs from OE suppliers, such as DENSO, who bring their OE competences to the aftermarket, without sacrificing performance, reliability or lifespan.
