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.

I have two Toyota Camrys. A 2004 SE and 2006 LE. Both have the same 4 cylinder engine. I have always been religious about checking the gas mileage on my cars at every fill up because this relays to me if anything has gone awry. The '04 had 115,000 miles and the '06 had 45,000 when I replaced the plugs. I replaced them mainly to see if it would help the fuel mileage; unfortunately for me, no difference. I'm sure they are good plugs as Bosch is well known for their high quality, however next time I will probably replace using the factory spark plugs.

Six month ago I popped these in my vehicle and the car continues to run smoothly and like new. I can't say that they increase performance in a noticeable manner, but I can say they didn't decrease performance. I'm happy overall.

These have been running strong now for 30,000 miles. They start the car 1-crank faster and have not given me any trouble. Fuel economy is what it should be as well.

I will purchase these again when they are worn. Finally, a good spark plug from Bosch!

-- Update --
It's now been a few more years and I've accumulated 60,000 on the plugs with no issues whatsoever. The mileage has been great, fuel economy is normal, and car still cranks quickly. I am replacing them as a regular tune-up only. These are so good that I'm buying them again!
