From the factory it breathes through four paper filter elements built for cost and long service intervals, not for flow.\u003c\/p\u003e\n\u003cp\u003eThe Dinan Drop-In Air Filter Set swaps all four for deep-pleated cotton filters that drop straight into the factory airboxes on the BMW F97 X3 M and F98 X4 M. On Dinan's flow bench each bank moves 1,022 CFM against 862 CFM stock at 28 in. H2O, an 18.6% airflow gain. Dinan measured maximum gains of 7 WHP and 8 lb-ft of torque at 4,750 RPM. For a filter change.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDinan Drop-In Air Filter Set Performance Without the Paperwork\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis is the easiest power you will add to an S58. No tune, no coding, no intake swap. The filters seat in the stock airboxes exactly like the paper elements they replace, and they also fit the Dinan carbon fiber intake if you upgrade later. Multi-layer cotton in deep pleats flows more while still filtering properly, and a steel wire mesh keeps each element from collapsing or denting.\u003c\/p\u003e\n\u003cp\u003eIt also stays legal. Dinan rates this set legal for sale and use on emissions-controlled vehicles, because it does not affect emissions and is not covered by emissions regulations. Dinan part number D403-0007.
