I have the K&N cold air box. It has a big mass air and a filter as large as the stock one. Everything unbiased I've read says it's of the highest quality. I've run them on 12 cars and trucks and never had a problem.
The K&N was worth a kick in the pants 20 to 25 HP.
Don't get one of the cone shaped filters as they are too small.
