Optiflow kit S40N/V50 Focus ST

The BSR Optiflow Filter kit consists of an open air filter and a custom-made shield, including all installation parts.
The advantages of the Optiflow filter are:
- The Sports Filter with low air resistance, gives quicker throttle response
- Ensures supply of cold and oxygen rich air
- Sporty intake sound, especially noticeable during acceleration (can be heard inside vehicle)
- Sporty engine compartment
- Washable filter components (cotton fabric)
- Delivered pre oiled and ready for assembly

The shield plate is made in Sweden and powder coated.

It is very important to follow the Maintenance Instructions for Performance Air Filter.
It must be cleaned and oiled at least every 10 000 - 15 000 km, depending on season and road type.
