Detailed Description

MotoRad 1IC358 is engineered to deliver stable ignition performance by maximizing spark voltage duration. That design helps maintain reliable combustion in engines that depend on precise coil output, especially in late-model Nissan and INFINITI platforms. This part number is a direct ignition coil replacement for applications including the 2009-2020 Nissan 370Z, 2008-2013 INFINITI G37, 2014-2019 INFINITI Q70, 2015-2019 INFINITI Q70L, 2014-2019 INFINITI QX70, and related models listed in the fitment data.

Built at ISO TS16949 manufacturing facilities, the coil is intended to meet OEM-level requirements for fit, form, and electrical performance. The design also addresses heat exposure common in engine compartments, making it a practical replacement when restoring ignition output on vehicles with misfire concerns or aging original coils. Part number 1IC358 is also referenced by 22448EY00A and 522143 for the same application.

What This Part Helps Address

• Engine misfire caused by weak or inconsistent coil output
• Hard starting related to ignition voltage loss
• Rough idle from degraded ignition performance
• Loss of power under load due to poor spark delivery
• Check engine light conditions tied to ignition coil failure

Installation Notes and Tips

Verify connector style, terminal layout, and engine application before installation. This coil uses a horizontal rectangular female connector and 3 blade terminals, and it requires an external resistor. Confirm the vehicle’s ignition system configuration matches the listed fitment before replacing the original part. For best results, inspect related ignition components and clear diagnostic trouble codes after installation if needed.
