Review on Hotwin Camshaft 12513P72003 Compatible Insight by Frankie Altamirano

As an automotive enthusiast I was excited to upgrade my camshaft for better performance. However, as a result of using this product, I found that the performance gains were negligible, and the engine sounded rougher than before. While the price was relatively affordable, I regret spending the money on a product that didn't deliver on its promises..
