Racingline R600 Cotton Filter Oversock

Racingline R600 Cotton Filter Oversock

The Racingline R600 Cotton Filter Oversock is a simple yet clever accessory designed to protect and extend the life of your Racingline R600 cotton air filter. It slips over the outside of the filter, acting as a first line of defence against the dust, dirt and debris that would otherwise settle directly onto the cotton element.

Cotton filters are well known for their excellent airflow, but they have one common drawback: as dirt builds up on the surface, airflow gradually drops and efficiency suffers. The single-layer foam oversock catches that debris before it reaches the cotton, helping your intake breathe consistently for far longer between cleans.

Why fit the Oversock?

• Protects the cotton filter surface from dust, grit and road debris
• Keeps airflow closer to “as new” for longer, reducing performance loss between services
• Easy to remove, wash and refit, or replace cheaply when needed
• Slides directly over the top of the existing R600 cotton filter with no tools required

How it works

Simply slide the foam oversock over your fitted R600 cotton filter. The foam layer traps the larger particles, while the cotton filter underneath continues to do its job of fine filtration. At each service, take the oversock off, clean it through with warm soapy water (or fit a fresh one), and your intake is back to optimal condition.

This is a low-cost way to preserve the long-term performance of a premium intake system, and it removes much of the hassle that comes with maintaining a high-flow cotton filter.

Important: This oversock is designed for the Racingline R600 cotton filter only. It is not compatible with the Racingline Tri-Foam filter.
