NGK 4793 Spark Plug

NGK Laser Platinum Spark Plug 4793

NGK Laser Platinum Spark Plug 4793 is a direct-fit ignition component built for stable spark delivery, consistent combustion, and OE-style service life. It uses a platinum center electrode, nickel ground electrode, and a 5,000 ohm resistor to support reliable ignition performance across a wide range of import and domestic applications.

The Laser Platinum line from NGK focuses on OE-level fit and durability, with a copper core center electrode for heat transfer and a standard ground configuration for dependable operation. This spark plug is a practical replacement for vehicles such as Dodge Neon, Subaru Impreza, and Kia Spectra applications that call for the specified heat range and gap.
