Bosch 8185 spark plug for the 2010-2013 BMW X5 V8 4.4L, the 2011-2018 X5 6-cylinder 3.0L and other vehicles ignites the air-fuel mixture in the cylinder with a fine wire, double platinum design. Like other Bosch platinum spark plugs, it has a platinum firing pin on the center electrode and a platinum inlay in the ground electrode, which reduces gap erosion.
- Laser-welded platinum inlay on the ground electrode for long service life
- OE Fine Wire design in the Bosch Double Platinum line requires up to 24% less voltage to ignite
- 360 degree continuous laser welding increases durability for increased life
- Copper core gives a broader heat range to resist pre-ignition and fouling
Quick facts
- Part: Bosch 8185 spark plug
- Fits: the 2010-2013 BMW X5 V8 4.4L, the 2011-2018 X5 6-cylinder 3.0L and other vehicles
- Condition: New
Hard starting, a rough idle or a misfire can be signs of a worn plug, though a failing coil or a fuel problem can produce them too, so find the cause before swapping parts. With the engine off and cool, a removed plug with a rounded or eroded electrode or heavy deposits shows what condition it is in.
