NGK 92217 Spark Plug

NGK Laser Iridium Spark Plug for Subaru

NGK 92217 is a Laser Iridium High Ignitability spark plug built for Subaru applications that call for precise ignition performance and a 0.032 in. gap. It uses an iridium center electrode, a dual fine-electrode ground design, and OE-style dimensions to match the factory service requirements on select Crosstrek and Impreza models.

The Laser Iridium High Ignitability line focuses on stable spark delivery and OE-level fitment for modern Subaru engines. For drivers searching for a Subaru Crosstrek spark plug or Subaru Impreza spark plug replacement, NGK 92217 provides the correct heat range, thread size, reach, and seat style for listed applications.

Detailed Description

NGK 92217 is engineered for Subaru vehicles that specify a high ignitability spark plug, including 2017-2024 Subaru Crosstrek and 2017-2023 Subaru Impreza applications listed in the fitment data. The Laser Iridium construction supports consistent spark delivery, while the dual fine-electrode ground configuration helps maintain the ignition characteristics expected in OE service intervals. This part cross-references Four Seasons 92217 for the same application.

Use NGK 92217 when replacing a worn spark plug on a Subaru Crosstrek or Subaru Impreza and you need the factory-style dimensions and gap specified for the vehicle. The part number 92217 is a direct reference for shoppers comparing OE-style ignition components by application and service interval.

What It Helps Address

• Rough idle caused by worn spark plug electrodes
• Hard starting from weakened ignition output
• Misfire conditions related to plug wear or incorrect gap
• Reduced throttle response from inconsistent combustion
• Service replacement for Subaru models with high ignitability plug requirements
