Want the ultimate from the R600 Cotton Filter? Protect your RacingLine R600 Cotton Filter!
Our new Cotton Filter 'Oversock' combines the best of both filter choices. The single layer foam material protects debris and dust from settling on Cotton Filter surface, and reduces the deterioration that all pleated cotton filters always suffer from.
Simply slide the foam oversock over the top of the foam filter and protect the surface layer of the cotton from dust and dirt.
When it needs it, the oversock can be cleaned or just replaced cheaply to keep the cotton filter at its very best for years.
