mountune V2 High Flow Air Filter

As part of our ongoing product development, we are always striving to improve our products and our new updatedV2 High Flow Air Filter for selected Focus models includes several enhancements that substantially enhance air-flow 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 air-flow 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 that creates a 10-15% increase in filtration surface area compared to other filters on the market.

The oiled filter media is incapsulated 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.

    Mountune highflow Airfilter V.2

    Very quick delivery, impressive. Opened the box and realised just how much improved the V2 is, over my original airfilter as supplied 3 years ago with the FPM375 installation. Better fit, obvious improved internal design, like the mountune logo plus my old one had seen better days.

    Much better!

    Excellent delivery time! Changes the sound and throttle response, no comment yet on the fuel economy.
