Description
DENSO's patented iridium alloy is extremely hard and wear-resistant. This makes it possible to produce a spark plug with a central electrode of only 0.4 mm, which produces a more intense spark and better ignition performance in any driving conditions. These spark plugs can withstand even the harshest conditions, and have proven themselves in original equipment and competitions. This product gives DENSO a leading position in the field of iridium spark plug technology.
