PSDesigns BMW S54 Velocity Air Filter Individual

Description Replacement Air Filters for our Increasingly popular PSDesigns BMW S54 Velocity Stack Conversion, the most complete conversion available for the BMW S54 Engine, as found in several BMW M Power Cars including the BMW E46 M3 and the BMW Z4M. The Tri-Foam System Why foam? Because, compared to paper or other filter technologies, reticulated polyester foam achieves optimum performance against three key criteria: Maximum Air Flow The ability to allow air to pass through without causing a large drop in pressure. Cleaning Efficiency The capability to arrest a high proportion of airborne dust while feeding the engine clean air. Dust Load-up Tolerance The capability to absorb a large amount of dust without reducing air flow capacity. Individual socks should be fastened down with a cable tie or jubilee clamp to hold them securely in place. Please note: price is per filter sold.
