As a hesitant automotive buyer, i decided to test out this pressure replacement FOR my Chevrolet. As a result of my tests I determined that this product did not live up to its claims. While it may have fit my vehicle perfectly fine, it did not improve the performance or driving experience in any way. The one pro was that it did not cause any damage to my car .However, the cons outweighed this benefit as it was a waste of money and did not offer any noticeable benefits..
