NGK 96457 Ruthenium HX Spark Plug FR5BHX High Ignitability

The NGK 96457 Ruthenium HX spark plug (NGK plug number FR5BHX) is a high-ignitability ignition plug for modern engines. It is a good choice as a direct replacement or as an upgrade to current OE-style plug technology. It has a fine wire ruthenium center electrode and a projected square platinum ground electrode (PSPE). Together they help burn fuel more completely, which gives quicker throttle response, a smoother idle and better cold starts.

Key Features:

• Ruthenium alloy center electrode: 0.6 mm fine wire design built for durability and ignitability at high temperatures
• PSPE ground electrode: The projected square platinum shape, with a cut-back design, improves ignitability and service life in high-heat engines
• Solid copper core: Improves heat dissipation and conductivity
• Trivalent metal plating: Resists corrosion and seizing, so installation and removal are easier
• Resistor design: 5k ohm resistance for suppressing radio frequency interference
