Product Review
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 Bosch IR Fusion in 3.5L Magnum, April 23, 2011

This review is from: Bosch (4508) FGR8LQI0 8 Platinum IR Fusion Spark Plug, Pack of 1 (Misc.)
One of the best if not the best Plug I ever installed. And I've been doing my own car maintenance for over 40 years. From when I first backed the car out of the garage I noticed a much improved throttle response. Now after nearly 1000 miles and checking mpg I can state that I have at least a 10% gain in gas mileage, thus after 3 tank fills I've paid for the plugs. Note, that I had 90,000 miles on the original 100,000-mile factory plugs, and they looked worn when I removed them. Now I know one does get appreciable gain in horsepower from plugs alone, but when your replacing old ones you will definitely get that WOW feeling when you mash that throttle down.

4.0 out of 5 stars Mixed bag, September 12, 2009

This review is from: Bosch (4508) FGR8LQI0 8 Platinum IR Fusion Spark Plug, Pack of 1 (Misc.)
I purchased these on the advice of a friend. They are replacing NGK Iridium IX spark plugs at around 90K miles on them. The NGK plugs went from the correct gap setting of .044 to .058 and had some signs of rust, it was time. They were being placed in the my 2002 Honda Odyssey which has 168K miles.

First off, these plugs are more fool proof to install since there is nothing to gap. They are suppose to get more spark at the tip due to the 4 electrodes. The end result is a mixed bag. I was really expecting my milage to go up a little like after the last time I replaced the factory NGK plugs with the IXs. What I got was slightly better Highway milage but over all my City milage had gone down a little. The car runs much smoother, sounds better, and definitely more drivable but the milage gain overall that I was hoping for was not there. Maybe it will take the Honda Computer more time to adjust to the different burn of the plugs. These plugs should not be any hotter or colder...Read more

3.0 out of 5 stars Bosch Platinum IR Fusion = SMOOTH & POWER but..., August 16, 2010
Amazon Verified Purchase(What's this?)
This review is from: Bosch (4508) FGR8LQI0 8 Platinum IR Fusion Spark Plug, Pack of 1 (Misc.)
Replaced in to my 2005 HONDA Cr-V. Smooth engine firing and acceleration power immediately noticeable. I monitored the fuel consumption, before and after installation. I found out that fuel efficiency went down, understandably, due to "increase" in power. See below:

Before installation: 19.99 MPG (average)
After installation: 18.54 MPG (average)

where MPG = miles per gallon of 87% octane gasoline.

Overall..happy with the new performance.
