Eddystar在国内的进气改装中，扮演着一个“救世主”的角色，一来国内专注于进气系统的厂商很少，Eddystar算是国内数一数二的厂商，同时质量也很可靠，二来国内自主品牌的新车发布接二连三，即便像K&N这样的大厂也无暇顾及，但是Eddystar就连一些非常偏门的自主车型都有配套的空滤和进气系统，完全不用担心找不到合适的型号。
 
The price of Eddystar's air filter is mostly about 300 yuan, using 4-6 layers of high-flow cotton yarn, supplemented by two layers of aluminum wire mesh fixation, plus filter oil, which improves the air flow while also blocking the entry of fine dust, and the frame at the edge uses integrated silica gel, which guarantees strength and durability. The official has a 100,000 km warranty, and it is recommended to clean it once every 5000-10000 km for daily use.
