Pipercross Panel Filter – Mini Cooper S
Unlike their competition, Pipercross have adopted multi layered foam technology for their air filters as opposed to cotton or paper. Why? Because foam has a larger capacity for filtration over cotton or paper. The low maintenance and long lifespan aspects of a Pipercross filter come from the special triple layer foam that is used on all Pipercross filters. The outer core is coarse foam designed to trap larger particles, the middle core is Medium foam designed to trap most particles and the inner core is fine foam which will trap the remainder of the particles. The triple layer foam design ensures an exceptional level of engine protection in any conditions.
