 We bought our Matrix because my wife fell in love with the design. After test driving it, we were sold on the leg and headroom. It was sluggish getting onto the freeway, so i went down to the local auto parts store and got a K&N air filter and it made an extreme difference. It has immediate acceleration and getting on the freeway is not a problem whatsoever! We are getting 35 MPG and it runs like a Toyota should. I would Highly recommend the K&N Air Filter! It makes a BIG difference.
