After installing a K&N air filter in my 2008 Smart Fortwo I noticed less hesitation during close navigation such as in parking lots and crowded neighborhoods where low speed movement is crucial.

I also noticed a slight improvement in acceleration.

I recently bought a K&N air filter for my 2007 Smart fortwo dsl.

The filter gave the car better power and throttle response, exceeding my expectations even for an engine of 45 horsepower.

Good work done by K&N

Thank you all
Hugo, Porto, Portugal
The product (PS-1008) and the mailing service are both excellent.  I get better acceleration, the oil stays cleaner longer and I end up having more fun driving my Smart Car.  I also really like the air filter cleaner with also improved my acceleration and mileage.  Thank you for a job well done.
