Denso spark plugs feature the smallest centre electrode allowing the spark to expand into a greater area thereby maximising firing performance and improving acceleration when comparing to normal spark plugs.
Iridium Power uses DENSO’s patented U-Groove ground electrode to achieve maximum ignitability while minimizing required voltage.
At 0.4mm in diameter, the DENSO Iridium Power center electrode tip is the world’s smallest.
Produces the hottest, most concentrated spark, while requiring the lowest voltage
Produces maximum performance under the most extreme conditions.
Features: Engineered with the smallest tip in the market
Delivering more complete combustion
Superior fuel economy
Designed to last beyond 100,000 km
0.4MM Iridium Centre Electrode
Low voltage requirement due to 0.4MM electrode
