My car always ran well. The new filter just makes it run even better. The stock filter was over twice as thick as the K&N and probably more restrictive.

Good quality and easy to install. The drivers side cut out however does not follow the shape of the trunk at all and has a 6" overlap piece that had to be cut by hand. The rest of the trunk shape was good.
