Bosch 9606 spark plug for the 1999 Ford F-150 V8 5.4L, the 2000-2008 F-150 V8 4.6L and other vehicles ignites the air-fuel mixture in each cylinder. It is one of the Bosch double iridium spark plugs, sold individually, and the engine needs one per cylinder.
- Fine wire double iridium design needs up to 24% less voltage to ignite
- Iridium firing pin and iridium ground electrode inlay for long service life
- 360 degree continuous laser welding for added durability
- Copper core gives a broader heat range to resist pre-ignition and fouling
- Tapered ground electrode that supports ignition throughout the life of the plug
