Smartmods Air Filter

Improved air filter for the 450 fortwo.

Smartmods air filter for Fortwo (old) and Roadster.

The thick 2 layer construction is the largest air filter you can get for the 450 and Roadster standard air box. The large size gives a much larger surface area than every other standard fitment filter on the market.

The filters come already oiled (for your pleasure) with Lucas foam filter oil. The oil is the secret ingredient for efficient filtering whilst still allowing full air flow.

The unique thing about these filters (at least when we 1st showed them off, but you know how people like to copy) is the special internal core that holds the filter in position and in shape. In a normal smart foam filter (ITG, Pipercross etc) you get a mesh tube that sits in the middle of the filter.
The problem with that is that mesh is only about 60% holes, meaning that you are getting a restriction in the possible air flow. We have used a steel spring for our filter core. This is 90% more open than mesh and the grade of spring steel means the core is a lot stronger than the mesh tubes. The springs are unfinished metal but do not rust or corrode.

These are not repurposed quad-bike filters as sold by many other manufacturers. The are designed and finished by evilution and manufactured in the UK.

They are very easy to clean at service time too. Just rinse them in warm soapy water before leaving them to dry naturally. Re-oil with any foam filter oil and reinstall it into your car.

We over-oil the filters in the bag to ensure a decent coverage by the time you get it. Remove it from the package and let it sit on its side on some paper towel for a few hours before fitting.
