I got a K&N filter to put in my Corsa C model 1.4cc and I liked the sound of the air intake. I believe that a possible increase of horsepower about 2 and 4 hp.

Since servicing my car and fitting the K&N filter I have gained 3 mpg already. The car runs more smoothly and drives better than before I fitted this filter.

A doddle to fit as a direct replacement for the standard filter. The improvements provided by this one little mod to my little Tigra twin top 1.8 have been excellent. I'm not so interested in ultimate top end power on the road, but the improvements in pick up from low revs and the improved acceleration are fantastic. The K&N filter has actually made the car easier, and more enjoyable to drive when I just want to pootle around, and provides much improved better throttle response and acceleration when I'm feeling a bit more feisty. It may have made the Tigra a tad more thirsty, but 50 of that could also be down to me enjoying the extra shove you get when you put your foot down now. Well worth every penny.
