Are you familiar with what a VTEC and a non-VTEC is? This refers to the engine of Honda cars. VTEC means Variable Valve Timing and Lift Electronic Control. This means that this will have overhead cams that will make sure that exhaust and intake will be possible.
When the VTEC is being used, you can hear the amount of air that is being used by the engine so that it will be able to pack up speed. Some Honda vehicles that do not have a VTEC engine will function the same way that a “normal” car will perform. It will still work, but it cannot be used for sports and racing.
