In the operating system of an automobile engine, the air filter plays a vital role—serving as both a "filtration barrier" that protects internal components and an "efficiency booster" that enhances power performance. Building upon this foundation, the 33-2405 air filter further redefines the functional standards of this component. Unlike common disposable paper filter elements, this product utilizes high-quality cotton gauze as the filtration medium, treated with a special oil-immersion process to form a multi-layered, fine filtration mesh.
