Product Description
Boschácombines the best features of their +4 plug with the advantages of iridium.áThe Bosch PlatinumIR Fusionáplug fuses iridium with platinum, combining the superior properties of both materials into a singleáfine wire center electrode.á Additionally this plugáusesásurface air gap technology and 4 yttrium enhanced ground electrodes for both performance and extra long life.áThe fine wireáiridium/platinum center electrode (which isáheat fused into the extended ceramic insulator) reducesáthe voltageánecessary to jump the gap as well as reduces quenching.ááTheá4 ground electrode design not only provides multiple radial spark paths,ábut also the surface air gap designácreates optimal exposure of the air/fuel mixture to the enhanced ignition spark. The combination of an iridium/platinum center electrode and the yttrium -enhancement of the ground electrodes even further extends plug life.áThis plug is designed toágive exceptional performance, reach self cleaning temperature faster for quicker starts, smoother acceleration and increased fuel efficiency.á

 great plugs w/two dollar rebate thru end of 2010 March 23, 2010
Tired of deception (CA)
purchased 4 of these for my RAV4 with 110k miles. Don't track MPG but I do drive 100-250 miles per day for work, gas tank does seem to need less filling.

Product arrived before promise date. Already knew how great the Bosch +4 Plugs were, and the IR Fusion plugs carry on the excellence.

I really liked the idea behind four electrodes. A bit pricey but with the rebate it made it a no brainer.

I've not installed the plugs in my Accord yet, but I can tell you delivery was prompt as always and packing was appropriate to protect the product.

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 than my other ones. Overall, for the drivablity and smoothness are better and there is a slight gain in highway mpg, but for some reason my city mpg took a small hit. I had not found anything on the web matching what happened to me but those are the breaks.
If I had the time and money I would like to try out the actually factory NGK plug vs the NGK IX vs these just to see if there is a real difference. Given the car has 168K on it these are going to be my last plugs that are installed. Overall more good than bad but not as good as I had hoped for. [...].
