Product Description
If you're looking for the very latest in spark plug technology, look no further than Bosch Platinum Ir Fusion. Fusion features a patented, fused 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.

As always Bosch products are great. BUT the shipping from this store leaves a lot to be desired!!! We ordered a set of 8. It took 4 shipments to receive all 8 Some were out of the boxes, some were packed in envelopes, some did not have any protective material around the electrodes. NEVER AGAIN!!!

I saved at least $20 with purchasing four of these items via Amazon.com. Product arrived fast and safe. Hassle-free installation. Definitely worth the money.
