Product Details
The NGK Laser Iridium High Ignitability spark plug line is built around OE-focused ignition performance for modern engines that require precise spark control. Part number 6215, also referenced as SILZKR6B11, is specified for select Hyundai and Kia applications including the 2011 Hyundai Elantra, 2009 Hyundai Genesis, 2010-2011 Kia Borrego, and 2009 Kia Borrego. This spark plug is engineered with a 0.044 in. gap and the listed heat range 6 configuration to match the original equipment requirements in those vehicles.
NGK has long supplied original equipment spark plugs for domestic and import vehicles in North America, and this part reflects that OE-oriented approach. This part cross-references AMS Automotive 6215 for the same application.
Common Issues This Part Can Address
- Hard starting caused by worn or inconsistent spark plugs
- Rough idle from degraded ignition performance
- Misfire conditions related to plug wear or incorrect gap
- Reduced throttle response from weak spark delivery
- Service replacement needs at the manufacturer-recommended interval
Installation Notes
Verify the vehicle application before installation and confirm the plug gap matches the engine specification. Use care when threading the plug into the cylinder head to avoid cross-threading, and torque to the vehicle manufacturer’s specification. For best results, replace spark plugs on engines that call for high ignitability plugs with the same plug type and heat range listed for the application.
Quality Assurance
NGK is a major OE spark plug supplier with decades of automotive manufacturing experience and a reputation built around original equipment standards. Part number 6215 is produced to support durability and operational performance in the listed Hyundai and Kia applications.
