NGK 5424 V-Power Spark Plug BKR4E-11 Nickel Alloy Resistor Plug 14mm

The NGK 5424 V-Power spark plug (NGK part number BKR4E-11) is a nickel alloy, resistor-type spark plug made to original equipment standards. It is an economical replacement ignition plug for engines that use standard nickel-tipped plugs. NGK describes its V-cut center electrode as improving ignitability compared with standard nickel plugs.

Key Features:

• V-cut center electrode: directs the spark to the edge of the electrode so it develops faster. This improves ignitability and reduces quenching.
• Copper core: helps remove heat from the firing end.
• Trivalent metal plating: resists corrosion and seizing. NGK states it eliminates the need for anti-seize.
• Alumina silicate ceramic insulator: gives strength, good heat transfer and dielectric performance.
• Corrugated insulator ribs: help prevent flashover.
• Triple seals: prevent combustion leakage.
• Cold-rolled threads: help prevent cross-threading and thread damage.
