Carbon Airbox Kit / Viper - Pipercross - BMW E30 323i 09/82 - 08/86

Originally developed in collaboration with Lotus for their legendary 340R, the Viper brings race-car technology to the road. Encased in carbon fiber to reduce intake temperatures, the reverse-flow filter offers fantastic airflow and filtration.

Equipped with a 75 mm cold-air feed, each filter includes a selection of neck adapters to fit 60/65/70/75 mm hoses.

Pipercross works closely with engine designers and, since every racing series is different, so are the foams. Other filtration media, such as paper or cotton gauze, cannot achieve this precise balance cost-effectively, making Pipercross ideal for competition production.
