Disappointing Camshaft for Automotive Performance

Had high hopes for this camshaft, but it fell short of expectations. After trying this product, my automotive engine still lacked the power I was hoping for. The installation process was difficult and required additional parts .The packaging lacked clear instructions and was confusing to follow..

Pros
  • The only positive is that it's a camshaft for automotive performance.
Cons
  • Difficult installation process, unclear instructions, and lacking power.

Cons
  • I vaguely remember
