Step 1 – Check your vehicle info: The 93815 spark plug fits for Kia & Hyundai L4 Engine (4-cylinder), includes 2012-2019 Rio 1.6L Naturally Aspirated, 2012-2019 Soul 1.6L Naturally Aspirated, 2012-2019 Accent 1.6, 2012-2017 Veloster 1.6L Naturally Aspirated, 2011 Elantra 1.8L
Step2 - Match the OE number: This spark plug can replace 93815, 92873, LZKR6AIX, SILZKR6B10E. OE number is usually on the original part or owner's manual. If unavailable, verify key specs and vehicle model to help determine fitment
Step3 – Verify key specifications: This set of 4 spark plugs features a copper center core with iridium tips, 0.035-0.039 in gap, 12 mm thread diameter, insulator height 2.01 in (50 mm), reach 1.043 in (26.5 mm), use a 15–20 N·m torque wrench for installation
How does this spark plug improve engine performance? These spark plugs feature a manufacturer heat range 6, which helps maintain optimal combustion temperature for more stable ignition; 5000-ohm resistance, which supports reliable spark energy and reduces electrical noise; and a 0.035-0.039 in gap, which assists more complete combustion to lower misfires and rough idling. Together, these parameters help improve engine efficiency, smoother power delivery, and overall driving performance
How to install spark plugs: Let the engine cool and gather basic tools. Remove old plugs one at a time, check and adjust the new plug gap if needed, hand-thread new plugs and tighten to the recommended torque, then reattach wires carefully. Avoid cross-threading, over-tightening, pulling wires, or working on a hot engine. After installation, start the engine and check for unusual sounds
