The Skunk2 thermal intake manifold has considerably improved the performance of my car. Thanks to my knowledge gained in practice I can easily tell the difference in power. The manifold is designed to reduce heat soak, ensuring that the engine works at optimal temperatures, thereby increasing horsepower. The only downside I found is that it's not easy to install .Nevertheless, this product gave my car a major boost in performance, and i highly recommend it to any car enthusiast looking to upgrade their ride..
