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: Fits my 99 Ford Taurus fine 2010-03-01
Comment: In conjunction with new Motorcraft plug wires i picked up a few horses and i think a tad better mileage so far. Have driven over 500 miles on them no engine codes or problems so they run fine. Went into my 99 Taurus with a Vulcan engine

Do yourself a favor. If you are considering these plugs, do a little research first and make sure you are going to get out of them what you hope. I didn't and now I'm paying for it.
I am not saying these are inherently bad plugs. It's just that these plugs don't perform well in my application.
