NGK Laser Iridium Spark Plug 97218
NGK 97218 is a Laser Iridium High Ignitability spark plug built for precise ignition performance and OE-style fitment. It uses an iridium center electrode tip, a dual fine electrode ground design, and a 0.040 in. pre-gap to support consistent spark delivery in the applications listed below.
The Laser Iridium High Ignitability line focuses on stable ignition characteristics and OE-equivalent design details. For drivers servicing a Cadillac SRX, Saab 9-4X, or Saab 9-5, this spark plug matches the specified high ignitability requirement and factory service interval guidance shown in the fitment data.
Key Features
- Laser Iridium High Ignitability spark plug for OE-style ignition performance
- Iridium center electrode tip for durable spark delivery
- Dual Fine Electrode - High Ignitability ground design
- 0.040 in. pre-gap for listed applications
- 14 mm thread diameter, 5/8 in. hex, flat seat
- 5000 ohm resistance
- Copper core center and ground electrode construction
- NGK part number 97218, manufacturer part number DILFR7B10G
Detailed Description
NGK 97218 is a spark plug engineered around the Laser Iridium High Ignitability design used in select OE applications. The iridium tip supports precise ignition at the specified gap, while the dual fine electrode ground configuration helps maintain consistent spark characteristics under normal engine operating conditions. With a flat seat, 14 mm thread diameter, 26.5 mm reach, and non-removable nut terminal, this plug follows the dimensional requirements called out for the listed vehicles. It is a direct service part for 2010-2011 Cadillac SRX, 2011 Saab 9-4X, and 2010-2011 Saab 9-5 applications that specify a high ignitability spark plug. This part cross-references GM 55564748 for the same application.
What It Helps Address
- Misfire concerns related to worn or incorrect spark plugs
- Hard starting caused by weak ignition output
- Rough idle from degraded plug performance
- Reduced throttle response from inconsistent spark delivery
- Service replacement needs at the OE-recommended interval
Installation Notes and Tips
Verify the engine calls for a high ignitability spark plug before installation. Confirm the gap is set to 0.040 in. for the listed applications and inspect the threads, seat type, and terminal style against the original part. Use proper spark plug service procedures and torque specifications for the vehicle. Fits 2010-2011 Cadillac SRX, N/A. Fits 2011 Saab 9-4X, N/A. Fits 2010-2011 Saab 9-5, N/A.
