Detailed Description

NGK DIS Ignition Coil 48620 is designed for vehicles using a distributorless ignition setup, where coil output must remain stable for reliable spark delivery. This coil is specified with a 12V electrical system, blade terminals, a female connector, and three terminals, which helps match the original electrical interface on the listed Subaru applications. If you are replacing a failing ignition coil on a 1997-1999 Subaru Legacy or a 1997-1998 Subaru Impreza, this part number 48620 provides a direct-fit service option.

This part cross-references Delphi GN10574 and Standard Ignition UF-193 for the same application.

What It Helps Address

• Engine misfire caused by weak or inconsistent coil output
• Hard starting related to ignition spark loss
• Rough idle from unstable ignition performance
• Intermittent stalling tied to coil failure
• Check engine light conditions associated with ignition faults

Installation Notes and Tips

Verify the connector style, terminal count, and ignition system type before installation. Confirm fitment by year, make, and model for the Subaru Legacy or Subaru Impreza listed above, and inspect related ignition components such as plugs and wiring for wear before replacing the coil. The coil mounts without an included bracket, so reuse the original mounting arrangement if applicable.

Quality Assurance

NGK manufactures this ignition coil to OE-level standards and validates designs in an ISO 17025 accredited test lab under demanding conditions. The brand’s long-standing OE legacy and broad vehicle coverage support confidence when selecting part number 48620 for Subaru ignition service.
