aftermarket intake cam sprockets. These do delete the VTC system. I believe your referring to BDE adjustable VTC sprockets that do retain the VTC system. The late model BDE sprockets allow you to adjust base cam timing and allow the ECU to control 10 degree's of cam movement, but only as a on/off control.
