I installed it a week ago and havent taken it out of four wheel drive since becuase of bad weather but it is getting two miles to the gallon better in 4x4 than it did before I installed the spacer. The whistle they speak of is like a brake squeal but only around 2,500 rpm and it isn't bad at all, most people probably would't notice it. Well made component. Worth the money in fuel savings.
