Denso® Double Platinum Spark Plug 3289

Denso Double Platinum™ Spark Plug are featured as follows:

• Electrode Made of Titanium-Enhanced Alloy.
• Minimum quenching electrode design.
• Enhances flame speed and thereby increases engine efficiency.
• Made up of the patented alloy iridium, which is six times harder and eight times stronger than platinum, commonly used in spark plugs.
• Can handle temperatures above 4,000°F.
• The firing end must be able to dissipate heat into the cylinder head as quickly as possible to avoid pre-ignition.
• Fine wire made of Iridium forms the central electrode.
• Platinum ground electrodes.
• They are designed for extreme temperatures exceeding 4,000° F associated with high-performance ignition and special fuel systems.
• Iridium is a currently utilized plug metal with the highest resistance to corrosion.
• Central electrode diameter is 0.4mm for improved ignitability and longer lifespan.
• Lasts more than three times what traditional spark plugs do.
• Factory-installed on today's latest high-performance and luxury vehicles.

It has a 1.1mm platinum center electrode and a titanium-enhanced alloy ground electrode that consumes fuel more efficiently and starts faster for improved fuel economy. The plug has minimum-quench electrode design and enhanced flame propagation to make the engine more efficient. The first automotive plug made using iridium, which is extracted from meteorites, can withstand temperatures higher than 4000°F surpassing any other material around. Besides, the company also uses innovative 360° laser-welding technology in their Denso Double Platinum™ Spark Plug 3289 such that they are able to withstand severe conditions. It is designed for longevity, providing more H.P., quicker easier starting, fewer heavy load misfires and better fuel efficiency.
