Detailed Description
NGK 49645 ignition coil is built to meet or exceed OE standards for durability and operational performance. The COP design places the coil directly at the spark plug location in distributorless ignition systems, helping maintain consistent spark output. NGK part number 49645, also identified as U5552, reflects the brand’s long-standing focus on ignition components and its OE-oriented manufacturing approach. This ignition coil is a direct service option for Subaru Forester, Subaru Impreza, and Subaru XV Crosstrek applications listed in the fitment data.
This part cross-references Davico Mfg (e.g., 49645) for the same application.
What It Is Used For
- Engine misfire caused by weak or inconsistent spark
- Hard starting related to ignition coil failure
- Rough idle from unstable coil output
- Loss of power under load from degraded ignition performance
Installation Notes and Tips
Verify the connector style, terminal count, and bolt-on mounting layout before installation. This coil uses a female connector, male blade terminals, and does not include mounting hardware or a mounting bracket. Confirm the vehicle’s ignition system is distributorless and match the part number 49645 or U5552 to the application listing before service.
Quality Assurance
NGK develops and tests ignition coils in an ISO 17025 accredited laboratory under demanding conditions. The brand’s OE legacy and global manufacturing network support consistent product quality for ignition service.
