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

Hey, these things really make my LS1 run a whole lot better.
By better, I mean better mileage and smoother performance.
I just bought them because I had 30K on the old ones. I was
surprised to feel a power difference.

These plugs seem to work well. I don't know if there is an hp or mpg gain but my engine is running quieter. The Bosch website make these seem like the best plugs ever. I hope so.
Fits my 99 Ford Taurus fine March 1, 2010

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
CAUTION!THESE PLUGS MAKE MY LS1 RUN HOTTER FOR SURE April 2, 2010

MSD Ignition 32819 Super Conductor Spark Plug Wire SetDEFINITELY GIVES MORE HORSE POWER BUT I SMELLED SOME BURING FROM MY ENGINE COMPARTMENT. I OPENED THE HOOD AND FELT EXTRA HEAT PLUS SMELLED ENGINE BURN. VERY CONCERNED WITH BURING MY ENGIE UP. SOMEONE PLEASE HELP! ALSO PUT ON NEW WIRES FROM MSD BUT THAT SHOULD HAVE NOTHING TO DO WITH SMELL OR HOTTER COMPARTMENT. PLUS THE COOLANT AND RADIATOR FAN WORK FINE.Bosch (4505) HGR8DQI Platinum IR Fusion Spark Plug, Pack of 1
