Foam filters take the idea of having larger holes and using oil to catch dirt particles as a cotton filter would, but by using a different format. The multilaminate reticulated foam uses layers of different specifications of foam, each later catching different sized particles whilst allowing the air to flow freely, stopping the loss of performance over time that other filters suffer from.
This great foam format was developed alongside race teams across the world, this form of development has enabled us to produce some of the most technologically advanced filters on the market. Using Pipercross's state of the art test cell, Pipercross check the flow rates of their panel filters are flow rates of over 1000 CFM (cubic feet per minute) as well as air depression readings, doing this as multiple stages of development allows us to test against the OEM filters. This allows us to create an improved aftermarket product that won’t affect your manufacturers warranty.
