Product Details

This ignition coil is part of NGK’s COP product line, which focuses on coil-on-plug applications where each cylinder uses an individual coil mounted directly at the spark plug. That layout helps maintain consistent ignition performance and simplifies service on vehicles such as the Toyota Prius, Toyota Yaris, and Scion xB. NGK’s manufacturing and testing process is built around OE-level standards, and the coil design is validated in an ISO 17025 accredited test lab under severe conditions before release.

This part cross-references Standard Ignition UF-316 and DENSO Auto Parts 673-1306 for the same application.

What It Helps Address

• Engine misfire caused by a weak or failing ignition coil
• Rough idle from inconsistent spark output
• Hard starting related to ignition coil breakdown
• Loss of acceleration response from intermittent coil performance
• Check engine light concerns tied to ignition system faults

Installation Notes

Verify connector style, terminal layout, and engine application before installation. This coil uses a female connector with male terminals and is designed for distributorless ignition systems. Confirm the vehicle match against the listed fitment before replacing the original coil on Toyota Prius, Toyota Prius C, Toyota Yaris, Toyota Echo, Scion xA, or Scion xB models.
