Detailed Description
NGK builds the 1582 spark plug to meet original equipment-style requirements for ignition systems that call for the CPR6EA-9S specification. The copper core helps support efficient spark transfer, while the nickel electrode materials and standard ground configuration provide a familiar service design for routine tune-up work. This plug is commonly searched as NGK CPR6EA-9S 1582 for vehicle maintenance and replacement planning.
For fitment-based searches, this spark plug is the type of part used when servicing vehicles that specify the NGK 1582 / CPR6EA-9S configuration. It is a practical choice for Honda and Acura applications that call for this exact plug specification, including searches such as Honda Civic spark plug replacement and Acura fitment by part number 1582.
What It Helps Address
- Misfires caused by worn or fouled spark plugs
- Hard starting from weak ignition output
- Rough idle related to degraded plug performance
- Reduced fuel economy from inefficient combustion
- Ignition noise concerns in properly matched applications
Installation Notes and Tips
Verify the vehicle’s required plug specification before installation, including thread diameter, reach, seat type, heat range, and pre-gap. The NGK CPR6EA-9S uses a 10 mm thread, .75 reach, flat seat, and .036 gap, so it should only be installed where those dimensions match the engine requirement. Use proper spark plug service procedures and torque to the manufacturer’s specification.
For Honda Civic spark plug replacement and Acura ignition service, confirm the engine application against the vehicle catalog before ordering. The part number 1582 is the key reference for matching the correct NGK plug to the intended application.
Quality Assurance
NGK is a long-established OE supplier and manufacturer with broad coverage across domestic and import vehicle applications. Its North American manufacturing and distribution network supports consistent product availability and OE-oriented standards for ignition service parts.
