BOSCH 4509 SPARK PLUG SET (8)

Latest in spark plug technology, Bosch platinum-iridium fusion spark plugs features a patented, fused iridium and platinum cetrew electrode, combined with ecclusive surface air gap firing technology to produce a longer, more powerful spark. It's four ytrium-enhanced ground electrode design outperforms OE iridium plugs by significantly reducing gap wear.
This means less stress on the ignition system for quicker starts, more efficient fuel cobustion, and a longer performance life. In addition, Fusion's voltage requirement increases less over time versus other iridium plugs for longer reliable performance of the vehicle's ignition system.
