NGK BKR5EYA Spark Plug – Stock No. 2087
The NGK BKR5EYA is a dependable nickel spark plug designed for smooth starting, stable idle, and consistent performance. It uses a V-grooved ground electrode to improve ignition, especially under light throttle and everyday driving. The projected tip helps the flame kernel start cleanly, aiding throttle response and fuel efficiency. It is a resistor type to reduce electrical noise that can affect radios and ECUs.
Use this plug where a 14 mm thread, 19 mm reach, gasket seat, and projected tip are specified. For vehicle fitment, please use the site’s vehicle lookup or check the Vehicle Fitment tab.
Always set the spark plug gap to your vehicle’s specification before installation.
