[Product Description] Our spark plugs are based on genuine plugs, but with upgraded materials at both ends of the center electrode and ground electrode. This significantly reduces electrode wear and ensures stable ignition performance over a long period. Furthermore, the ultra-thin electrodes allow for lower ignition voltage, superior ignition performance, improved combustion efficiency, and more stable idling. As a result, benefits such as improved engine response, better fuel efficiency, and longer lifespan are achieved.
[Compatible Vehicles] Suitable for vehicles such as the Nissan Dayz (B21W), Nissan Dayz Roox (B21A), Mira e:S (LA300S, LA310S, LA350S, LA360S), and Mira (L275S, L285S, L275V, 285V). Please check the product images for details. *Note: Even with the same vehicle model, there may be a small number of vehicles that are not compatible due to differences in year, engine type, etc. Please carefully check the product images before purchasing to confirm the product's appearance and compatibility attributes.
[Reference Compatible Part Numbers] Applicable only to vehicles with one of the following part numbers installed: LKR6ARX-P, 90048-51211, 90048-51207, or 90048-51218. *Note: This product is based on the genuine spark plug, with the electrodes at both ends upgraded to iridium material. While the compatibility is the same, it is not manufactured by Denso or NGK. Please check carefully before purchasing.
[Deterioration Symptoms] We recommend replacing the spark plug promptly if any of the following symptoms occur: ① Difficulty starting the engine: If the engine is difficult to start due to poor ignition. ② Reduced power: If you feel a lack of power during acceleration. ③ Decreased fuel efficiency: If fuel efficiency decreases and fuel economy worsens. ④ Unstable idling: If you feel vibration or instability when the engine is idling.
[After-Sales Service] This product comes with a 3-month warranty from the date of purchase. If you have any problems during the purchase process, please contact us by email at any time. We will reply within 24 hours.
