I originally used a K&N drop in filter in my 91 LX. It didn't give a real noticeable increase in horsepower if any, but it definitely did make it sound better. I then upgraded to a K&N cold air intake system which replaced my factory air box, I noticed very little difference between the two, in sound or power.
