I put K&N filters in every vehicle I own from right when I purchase them... Best filter on the market... Takes the flat spots out of acceleration and increases performance and gas milage.

Easy direct replacement for Vauxhall filter and has certainly improved engine performance, ironing out previous flat spots and giving more acceleration and pulling power in higher gears.

Any spark owner knows it needs all the help it can get when it comes to power. The K&N filter helps, as expected. It not only adds a bit more power, but it helps with quicker throttle response as well. When bumping up the cruise control speed, it gets there quicker & helps smooth out the lag off the line also. I haven't had it long enough to have any input on fuel mileage but will update this if there's any noticeable difference.
