The 33-2443 employs a layered oil-impregnated cotton gauze media, meticulously engineered to balance maximum airflow with exceptional filtration performance. The cotton gauze layers undergo precise oil impregnation, forming a viscous barrier that captures even minute contaminants (down to 2.5 microns) while permitting a steady flow of clean air into the engine. This optimised airflow enhances fuel combustion efficiency, delivering a significant boost in horsepower and acceleration performance – making your driving experience more responsive and dynamic.
