Bosch (4504) HGR9DQI Platinum Ir Fusion Spark Plug, Pack Of 1
- Revolutionary surface air gap firing technology featuring Bosch's unique four ground electrode design delivers the most powerful spark for the most efficient combustion and optimum horsepower without increasing the voltage requirement
- Fusion's voltage requirement increases less over time versus other iridium plugs for longer reliable performance of the vehicle's ignition system
- Fused iridium and platinum center electrode, sintered into an extended insulator nose results in reaching self-cleaning temperature only seconds after starting and provides exceptional wear resistance
- Factory pre-set gap allows for easy installation that never requires adjustment
- Four yttrium enhanced ground electrodes resist spark plug wear and oxidation for exceptional performance life
If you're looking for the very latest in spark plug technology, appear no further than Bosch Platinum Ir Fusion. Its 4 yttrium-enhanced ground electrode design outperforms OE iridium plugs by substantially reducing gap wear. This implies less stress on the ignition system for quicker starts, a lot more efficient fuel combustion, and a longer performance life. Fusion features a patented, fused iridium and platinum center electrode, combined with exclusive surface air gap firing technologies to produce a longer, a lot much more potent spark. In addition, Fusion's voltage requirement increases less much more than time versus other iridium plugs for longer reliable performance with the vehicle's ignition system.
