mountune High Flow Air Filter Focus ST/RS
mountune High Flow Air Filter Focus ST/RS
SKU:2363-AF-AA
The Mountune V2 High Flow Air Filter for the Focus ST and RS includes several enhancements that substantially enhance airflow compared to the standard filter and even our previous version.
Improvements include a unique smooth radius in the primary inlet port providing an efficient transition for airflow along with a shorter inner filter cone to allow maximum air velocity and flow directly to the inlet port.
These updates coupled with double-layer cotton gauze with deep pleats create a 10-15% increase in filtration surface area compared to other filters on the market. The oiled filter media is encapsulated in steel mesh that helps to maintain the perfect shape under the most extreme conditions. Each mountune filter is manufactured using a four-step process resulting in a precision fit and virtually no seepage of rubber frame material into the filter media producing the maximum available filter area.
Please note for Focus RS, replacing the original air filter with a high-flowing unit may cause a whistling type of noise on some vehicles. Please see our Sound Suppression Chamber for more details.
