Product Details

As part of NGK’s Laser Iridium High Ignitability line, this spark plug is engineered for vehicles that call for a high-ignitability OE replacement. NGK has long supplied original equipment spark plugs for domestic and import vehicles in North America, and this plug reflects that OE-focused approach with durable materials and precise electrode geometry. It is a strong match for drivers searching for an NGK 97080 spark plug for Hyundai Elantra, Kia Forte, Kia Soul, Kia Sportage, and related models.

This spark plug uses an iridium tip for the center electrode, a copper core for both center and ground electrodes, and a tapered ground electrode tip design to help maintain dependable ignition characteristics over the service interval. The flat seat and 26.5 mm reach support proper OE-style fitment where specified.

This part cross-references NGK SILZKR8E8G for the same application.

What It Helps Address

• Hard starting caused by worn spark plugs
• Rough idle from weakened ignition performance
• Misfire conditions related to electrode wear
• Reduced fuel economy from incomplete combustion
• Loss of throttle response from inconsistent spark delivery
