-
The VTEC system changes the cam profile to correspond to the engine speed. It maximizes torque at low engine speeds and output at high engine
speed.
-
The low lift cam is used at low engine speeds, and the high lift cam is used at high engine speeds.
-
The K20A2 and K2OZ1 engines change both the intake and exhaust camshaft. Only the intake camshaft side has a VTEC mechanism on the
K20A3 engine.
