Pipercross PP1301 sport air filters for BMW 7 Series E32 730i from 12/1986 to 09/1994

Explanations and operation:

PIPERCROSS is the world leader in high-tech polyurethane foam filters.

PIPERCROSS air filters promote 30% more air passage than a paper filter. Each filter is composed of 3 layers of foam of different density, from the largest to the smallest.
The foam frame has a reticular cut cell structure. This structure is produced chemically, then by strictly controlled combustion, offering precision ranging from millimeters to microns.

Why PIPERCROSS filters more efficient?

Thanks to these three layers, PIPERCROSS filters collect coarse impurities outside without clogging the lower layers. Even in a dusty environment such as in a rally race, the foam filters sustainably maintain high performance. This is why 100% of teams use foam filters in Rally Crosscar.

HIGH-TECH PIPERCROSS

PIPERCROSS exclusively offers HIGH PERFORMANCE air filters specific for TDI engines which operate without oil. Everyone knows that some TDI engine flowmeters are fragile from the outset. The use of an oiled filter aggravates this fragility by lubricating the hot wire. Thanks to its mastery of multi-layer variable screen filters, PIPERCROSS is the only manufacturer to offer this technology which preserves the flowmeter and therefore maintains the manufacturer's warranty.


ECOLOGICALLY "FRIENDLY"

PIPERCROSS filters are guaranteed for life and therefore should not be replaced but cleaned. Thanks to their low clogging, PIPERCROSS filters require much longer cleaning than oiled cotton filters. Indeed, maintenance is done every 15,000 km instead of 5,000 for a cotton. Finally, the marked improvement in engine efficiency obtained by better air flow makes it possible to significantly reduce energy consumption.
