• Ease Of Installation - Never Requires Adjustment
• Four Yttrium Enhanced Ground Electrodes
• Fused Iridium And Platinum Center Electrode, Sintered Into An Extended Insulator Nose

If you're looking for the very latest in spark plug technology, look no further than Bosch Platinum IR Fusion. Fusion features a patented, fuse iridium and platinum center electrode, combined with exclusive surface air gap firing technology to produce a longer, more powerful spark. Its four yttrium-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 combustion, 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.
