Description

The Denso 4703 Iridium TT spark plug is designed for extended longevity, offering a lifespan of over 100,000 miles. It features Denso's Twin-Tip technology, combining a 0.4mm iridium center electrode with a 0.7mm platinum ground electrode to enhance spark energy concentration and ignition. This design aims to improve acceleration, torque, and fuel economy. The plug incorporates machine-rolled threads to prevent seizing and a purified alumina powder insulator for strength and thermal conductivity.
