One simple change to improve fuel efficiency
Replacing an older style spark plug with a more technologically advanced component can result in fuel efficiency improvements of between 1% and 3%.
This may not seem like much, but over the course of years, this adds up to considerable savings.
Unique design carries big impact
Traditional spark plug design includes two flat surfaced electrodes, which create the ignition spark within a compact space with limited room for the ignition flame to grow, reducing the potential for combustion.
In comparison, DENSO’s Iridium Twin Tip (TT) Spark Plugs are designed with two needle-thin electrodes, which allow the flame to grow by 360 degrees in all 3 dimensions. This unique design enables the flame to expand more quickly and effectively, resulting in a more powerful combustion and better engine performance.
DENSO AM have carried out extensive trials, lab-testing a car engine’s fuel consumption using different types of spark plugs, both their own designs and competitors’. The results clearly show that the more space there is for the ignition flame to grow, the better the engine performance. Under full load for example, the Iridium TT spark plug reduced fuel consumption and CO2 emissions by up to 3.4%i.
When you use an Iridium TT spark plug, you improve both fuel efficiency and engine longevity. Whereas older spark plugs last around 40,000 km, Iridium TT spark plugs will continue to perform after 120,000 km.
The combination of Iridium TT’s advanced design with a unique iridium rhodium alloy makes spark plugs more efficient and improves vehicle performance. “I have used other spark plugs in the past but 15 years ago I made the change to DENSO. The difference was clear from the first start, with a smoother idling and better performance through the gears,” said Greg Shaw, an installer for a UK garage.
Improvements in the combustion performance of spark plugs also reduce CO, CO2 and HC emissions, meaning that a spark plug upgrade is better for the environment too.
DENSO AM assures quality spark plug production
All of DENSO’s Spark Plugs, whether they’re for the Aftermarket, OES or OE, originate from the same production lines. This allows DENSO Spark Plugs to be rigorously tested as part of a standardised manufacturing process.
“By focusing on the quality of our manufacturing process, we ensure that each of the spark plugs that leave our production lines is reliable and will provide optimum performance,” said Gilbert Couvert, Product Manager, Spark Plugs at DENSO Europe Aftermarket.
