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

Summary: Bosch Platinum IR Fusion = SMOOTH & POWER but... 2010-08-17

Summary: Terrible Packaging 2010-06-08
Comment: I rate this as poor as I just received the spark plugs five days late and the box smashed and half open. It looked as if a truck drove over the small box? It was a wonder I got all eight plugs and was very disappointed in whoever packaged these plugs as it was the worst I eve have seen. There was no protection if the shipping box was damaged. I have waited and waited for these plugs and when I get them, they are smashed. Not bad plugs, but terrible packaging and makes me wonder about Amazon.

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

Comment: 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.
