as claimed it is a quiet spacer. does make a difference in mid range power(ie passing on the interstate) and seems to have brought my mpg. up about 3/4 a gallon avg. instructions are a little vague, but called JET and got fast tech support. the tech guy was real helpful and as nice as could be. over all, good prod. and will be shopping with autoanything again.
