Bosch 4501 Platinum IR Fusion Spark Plug
I just installed these in my new Yaris. It was a quick installation and once I put them in, I took the Yaris out for a test drive.
I did this to see if the Bosch 4501 Platinum IR Fusion Spark Plugs would provide better gas mileage because some of the customer comments mentioned the increase in mileage as well as better performance. Almost instantly, I noticed the increased power. The car was quicker off the line and seemed to have more power all the way up the automatics shift cycle. I drive weekly to Chicago and back so I will be able to quickly see if there is any difference in the MPG.

I used the Platinum +4's for 50,000 in my 2002 Echo (before the IR Fusion were out) and noticed a lot more zip and new life. Mileage was marginally better maybe .25-.5 mpg increase over the stock plugs.

More power better and gas mileage due to different spark plugs?i suppose if you use premium gas and a few additives you will get even more power.Boggles the mind at Just how much power is possible?

Well I had my first trip with the new plugs. I think I am a little disappointed. I drive 70MPH and have gotten some rotten mileage lately and was hoping the change of plugs would make a big difference. I drove from Indy to Chicago and was about 50 miles from home when I reached the blinking led of my last gas bar. I filled up and the mpg was right at 36 MPG. Of course there could be a lot of variables in this...temperature...gas pump...but overall, I was not a happy camper!

Was this the first fill up after installing the new plugs? If so, tell us how the next few tanks are.
I doubt you'll see a huge increase in mileage because you have an 09, so the old plugs were probably in good shape. |

I am tempted to get a scan guage to be more accurate, but I have a hard time justifying almost $175 for something that could pay for my gas for almost two months.

Please provide mileage logs for at least 3 tanks before you changed the plugs out, and for at least 3 tanks after the changeover. You may need to track for a longer time to find the true difference, if there is indeed a difference. Even then we'll need to weigh the cost of the plugs and their lifespan versus any fuel economy gains.
I participated in a manufacturer's test for better MPG with the Pulstar plugs and they made not one iota of difference over the stock plugs despite costing 8x more, so I am skeptical.

As for the plugs not being worth the cost, you might be right. The plugs do provide better power....so if that was the only difference, it would be worth it. I would love it if there were better gas mileage.

And do you realize that you just came into a fuel economy forum and said that getting MPG really doesn't matter as long as you get more power?

I do not appreciate your smartass remarks but I will respond to your question in the hopes of creating an understanding. I will simply detail why folks around here tend to listen to me when it comes to fuel economy.
1) All of the fuel economy related stickies in here are mine. 2 of them were stickied in the general forum for more than a year before this forum was created. 2) I discovered both DFCO (and how to exploit it) and the "Hang Time" technique, both of which have been adopted by the hypermiling community as a whole. 3) For more than a year I held every known record for fuel economy in the gasoline-powered Yaris and helped to educate the few folks that finally beat me. I still hold the record for the longest distance tank (562 miles). 4) I have participated in both the fuel economy version of the re-enactment of The Great Race where 6 of us set several new world records using 2 hybrids loaned to us by Honda and in the first annual World Fuel Economy Championships where I placed 3rd overall in the Honda Insight and 5th overall in the Toyota Prius. 5) I am repeatedly asked to help manufacturers test their offerings for fuel efficiency. 6) I have been interviewed by and featured in several local and regional news casts and publications as well as a Next Gear podcast. As you can see this is a subject that I know a thing or two about, and one that I am passionate about. I will always welcome new ideas from folks but saying that something increases fuel economy without the proper testing to show it definitively only spreads disinformation in a field that is already littered with misunderstandings and lots of snake oil. I simply work to mediate the flow of information in order to separate the real from the wishful for the benefit of us all. It seems that you are interested in fuel economy and that you are willing to try new things. I applaud you on both counts and again encourage you to begin logging your mileage not only so that you can properly test your ideas out but also so that you can track your own progress over time.

Maybe that should be the fuel Miscount.

There is a little difference between asking for something and demanding it. As with most creatures on this earth, I give more when the tone is a kind one. When someone is telling me to do something and then questioning me like I am child, I will respond in kind.
