VTC Killer Adjustable Cam Sprocket:

-Because the K20A engine`s VTC (continuous valve timing control mechanism) is set to work only standard camshafts, there is a risk in possible camshaft timing problems to occur when aftermarket camshafts are installed. With the VTC Killer Adjustable Cam Sprocket, the VTC mechanism is locked into place and made completely adjustable to the needs of the user, making installing and valve timing with aftermarket camshafts completely safe!

Cam Dynamic Damper:

-Installing the VTC Killer Adjustable Cam Sprocket may cause instability on the K20A`s Chain Tensioner because of additional weight added to it. Use the Cam Dynamic Damper that is included in this set to ease the weight on the Chain Tensioner.

***This listing has the option of purchasing this set for either the Exhaust or Intake side of the K20A. Please specify for which you wish to purchase this product.
