Overview
NGK Spark Plug 4632 is a standard replacement spark plug built with a copper center electrode core, nickel center and ground electrode tips, and a 5,000 ohm resistor. It uses a flat seat, 14 mm thread diameter, 0.5 in reach, and a .028 pre-gap for applications that call for this specification.
As part of NGK’s Standard Spark Plug line, this plug reflects the brand’s OE-focused manufacturing approach and long-standing coverage across domestic and import applications. The NGK 4632 is identified by part number BPR6HSA and stock number 4632.
Key Features
- Copper core center electrode for consistent ignition performance.
- Nickel center and ground electrode tips with standard ground configuration.
- 5,000 ohm resistor helps control electrical noise in the ignition system.
- Flat seat design with 14 mm thread diameter and 0.5 in reach.
- Pre-gapped to .028 for applications that specify this setting.
Detailed Description
The NGK 4632 spark plug is engineered for vehicles that require a standard copper-core plug with nickel electrode materials and a stud terminal. Its 13/16 hex size, 53.00 insulator height, and heat range 6 make it a direct-spec replacement for engines that match these dimensions and electrical requirements. For buyers searching for an NGK BPR6HSA spark plug or NGK 4632 spark plug for ignition service, this part provides the core specifications needed for proper fitment and operation.
NGK’s Standard Spark Plug line is built around original equipment standards and broad application coverage. That makes the NGK 4632 a practical choice for routine ignition maintenance where the correct heat range, seat type, and electrode construction matter. It is commonly searched for as an NGK spark plug for domestic and import vehicles, including Honda Civic applications when the engine specification matches this plug.
What It Helps Address
- Hard starting caused by worn or incorrect spark plug specifications.
- Misfire concerns related to electrode wear or improper gap.
- Rough idle from degraded ignition performance.
- Reduced combustion efficiency from an aged plug.
- Electrical interference in ignition systems that require resistor plugs.
Installation Notes
Verify the required heat range, thread diameter, reach, seat type, and terminal style before installation. Confirm the specified gap for the engine and check that the plug matches the original service part number or OE specification. This part cross-references Monroe Shocks & Struts (e.g., 98076-56715, W20FP-L) for the same application.
