NGK Spark Plug Stock # 93482

The NGK Spark Plug Stock # 93482 is a precision ignition component engineered for reliable engine starting and consistent combustion performance across a wide range of automotive applications. As a mechanic, you know that spark plug selection directly impacts fuel efficiency, throttle response, and overall engine longevity—making OEM-grade replacements essential for both daily drivers and modified builds. NGK's reputation for quality manufacturing means this spark plug delivers the dependable ignition characteristics your engine demands, whether you're maintaining stock compression or running a tuned setup.

This NGK spark plug features advanced electrode geometry and ceramic insulation designed to withstand high combustion temperatures while maintaining proper heat range for your specific engine. The iridium or premium metal construction resists erosion and fouling, extending service intervals compared to conventional copper spark plugs and reducing the frequency of replacement maintenance. NGK's manufacturing tolerances ensure proper gap consistency and reliable spark initiation, critical factors that prevent misfires, stumbling at idle, and performance loss under load or sustained acceleration.

This spark plug is ideal for owners performing preventive maintenance, tuners validating baseline ignition health before bolt-on modifications, or technicians servicing fleet and consumer vehicles requiring OEM-equivalent performance. Installation is straightforward—verify your engine's heat range requirements and existing gap specification before installation to ensure optimal combustion and prevent detonation or lean-burn issues. The lightweight, compact design (0.09 lbs, 3.9-inch length) fits standard spark plug bores, making it a direct replacement option for applications specified in your vehicle's service manual or shop reference guide.
