XU22EPR-U 3179 通用型火花塞，适配丰田普锐斯等多款车型

XU22EPR-U 3179 universal spark plug (not directly corresponding to OEM numbers) but widely used as a mainstream replacement; compatible with many brands’ ignition systems. Its core function is to generate electric sparks to ignite the air-fuel mixture, ensuring normal engine operation. Compatible with post-2000 Toyota Prius, Audi, Mercedes, Mitsubishi, Subaru, Kia, Honda, and other models. If your car experiences starting trouble, hesitation during acceleration, or high fuel consumption, replacing with this plug can effectively resolve and restore smooth power output. Idle jitter or weak acceleration is usually due to worn spark plugs.
