Review on Hiflofiltro HFA3605 Premium Replacement Filter by Greg Simms

Don't worry about OEM or "washable" foam filters for your road bike, they offer better filtration than foam and are ideal for a lot less money than OEM. I wonder how many motorcycle owners switch to high performance, high flow foam filters to save money over ridiculously expensive OEM filters, not knowing that they are sacrificing engine life to get that extra flow. Just lift the foam filter and look through on a sunny day; You can see the light shining straight through - sure, MOST dirt will be attracted to the oil film if properly cared for; Are you sure you remember to clean and oil it regularly with the right oil? Even with perfect care, the foam does not hold back as much dirt as the physically dense fiber mesh in this filter. If your engine requires maximum airflow for maximum performance, you should be racing anyway and planning on regular engine repairs - buy a foam filter. If you need stable, trouble-free operation for a long time, BUY THIS FILTER!
