Your engine is an investment that deserves the best possible protection, but we know you shouldn’t have to sacrifice performance to get it. To show you exactly how our hardware performs in the real world, our engineering team has compiled this guide based on rigorous, data-driven filtration testing.
In summary, our dry media filters provide 99% efficiency for normal on-road daily driving and spirited light off-roading.
Modern engine air filters must balance two critical characteristics: airflow and filtration efficiency. Using ISO 5011 / SAE J726 laboratory testing standards, the SXTH Element filter demonstrated up to 99.52% filtration efficiency while maintaining low initial restriction at 300 m³/h airflow. Industry-standard ISO 5011 testing evaluates differential pressure, airflow restriction, and particulate capture under controlled laboratory conditions, allowing for a direct comparison between filter designs.
Research and filtration industry data also show that particles at or above approximately 1 micron are commonly associated with accelerated wear on the intake tract and engine components; this is why the graph highlights performance within that critical particle range.
