I have a Tall valve train with a stud girdle. The regular breather, and my valve covers would not allow me to barely push in a breather. This alleviated the problem by lifting the breather up away from the valve train.

The only thing that I wish was different is that the baffling was in the middle of the tube. It would make adding oil much easier.

This was a good price for the product. There isn't a lot of trickery here. Its what I expected, and bought the same product to update my other valve covers. Good bang for the buck.
