Original spark plugs for GMC + Tahoe + Serena set 2015-2020

The original spark plugs for GMC, Tahoe, and Sira cars from 2015 to 2020 are the small part that generates a high-voltage electrical spark inside the combustion chamber to ignite the fuel-air mixture, resulting in combustion that powers the engine. The importance of the original spark plug lies in being the primary responsible for starting the combustion process at the correct timing for each cylinder, ensuring engine power, throttle response, fuel efficiency, and reduced harmful emissions, with full compatibility with factory specifications. The high-quality heat-resistant insulating material, the corrosion-resistant metal electrode, and the precise gap design ensure a strong, steady spark and a long lifespan. Replacing the damaged or worn spark plug, which has become weak or intermittent, restores engine power and smooth operation, immediately eliminating any engine vibration, difficulty starting, or increased fuel consumption, so your car runs efficiently and energetically. **Specifications** - Compatible models: GMC 2015 – 2020, Tahoe 2015 – 2020, Sira 2015 – 2020 - Part name: Spark plug - Original - Set - Storage number (SKU): 41-114GM
