Pipercross air filters consistently outperform paper and cotton-gauze rivals to supply air to the engine – even when dirty! This is thanks to the multilaminate construction used in every Pipercross performance air filter. Layers of varying porosity foam all work together to trap different sized particles. Pipercross motorcycle air filters have been repeatedly tested on many different motorcycle configurations and the results speak for themselves. An increase in both power and torque. The need to modify fuelling, all by simply replacing the air filter unit. Through extensive research and testing using the SAE J726c air cleaner test, we have developed the perfect combination of filter density and thickness for each layer within the air filter. Where Pipercross filters are impregnated with the dirt retention additive, the filtration performance is greater enhanced as the additive helps the foam to swell, opening the cells whilst providing a “sticky” layer to hold more dirt. At Pipercross, our performance air filters are also tested on independent state-of-the-art engine Dynamometers and the results speak for themselves with the graphs below showing both horsepower and torque figures in comparison to the standard air filter and intake system.
