What are the benefits of the replacement filter?

The Ramair replacement air filter is made of high-quality, double-layer Aeriform foam—a material also used in professional motorsports. The special foam structure combines maximum air permeability with excellent filter performance. Thanks to its precise fit, the filter is not only easy to install but also low-maintenance in the long term.

Thanks to its high-quality materials and sophisticated construction, this air filter not only provides improved airflow, but also a longer service life than conventional paper filters. Ramair air filters use a completely oil-free technology – for top performance and extended service life. Thanks to the oil-free design, no re-oiling is necessary, which significantly reduces maintenance requirements. Another advantage: Your vehicle's mass air flow sensor remains free of oil-based residues. This prevents faulty sensor readings that could lead to a drop in performance. As a result, you benefit from constant engine power and reliable vehicle performance.
