Review on GM Genuine 89017368 Engine Manifold by Pule Sabando

After I put it to the test this engine manifold proved to be a complete letdown. Despite ITS claims of improved performance, my car actually performed worse than before .The only positive thing I can say is that the installation process was relatively easy. However, the cons definitely outweigh the pros with this product. I wouldn`t recommend it to anyone looking for true performance enhancements for their vehicle..
