VTC, generally refered to as variable valve timing (VVT) , advances and retards camshaft timing based on various factors including rpm, engine load, throttle position, etc. While this system works well with standard camshafts, when upgraded racing camshafts are used, the system limits performance. The TODA VTC Killer campulleys eliminate the VTC function of the K20A engine. Essentially, they remove "i" from i-VTEC.
