Genuine Spark Plug for the 2016–2021 Honda Civic with the 1.5L turbo I4 (L15B7)
This is a new, genuine Honda spark plug with OEM part number 12290-59B-003, engineered for the 1.5L turbo I4 (L15B7) engine in the 2016–2021 Honda Civic. Worn plugs make the coils work harder and cause misfires, hard starts and lost fuel economy. Use the factory heat range and gap specified for this engine. Mason’s Auto Store sells it 30% below the manufacturer’s suggested retail price and ships it across the USA from our Battle Creek, Michigan warehouse.
Catalog fitment notes: 1.5L turbo with automatic transmission.
