Key Features and Specifications
The Bosch 9619 spark plug features a double iridium design that offers higher performance and up to four times longer life compared to standard copper spark plugs, according to Bosch.
Electrode Material: Features an iridium-alloy center electrode firing pin and a laser-welded ground electrode with an iridium alloy inlay.
Design: The ultra-fine wire design and tapered ground electrode provide better ignitability and performance.
Ignition Voltage: The design requires up to 24% less voltage to ignite, which improves engine efficiency.
Durability: A copper core provides a broader heat range to resist pre-ignition and fouling, while a nickel-plated shell and rolled threads offer anti-seize and corrosion protection.
Installation: The spark plugs come pre-gapped from the factory, allowing for straightforward installation without the need for gap adjustment or anti-seize compound.
