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.

5.0 out of 5 stars Good Plug - However, No Noticeable Fuel Mileage Increase, March 6, 2009

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.

5.0 out of 5 stars love these plugs, November 4, 2007

I muat admit. I never did a tuneup on my 2002 Camry, I'm ashamed to say. time just got away from me. Then I noticed I was going to the pump far more often than I should. That forced me to think about a tuneup and replacing my plugs. Fortunately, I thought to spend the extra few dollars over the champions. No disrespect to them, but I just figured I'd put in the best since I was spending so much at the pump.

I put the these Bosch's in and boy oh boy!! I just had to check my consumption. I was averaging 32mpg after this tuneup procedure.

i'm satisfied. Never saw this type design before. Awesome!! worth every penny.

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.
