In some cases the manufacturer will limit the power that a vehicle produces due to insurance limitations, emissions restrictions or sound/comfort specifications.
Well engineered aftermarket components will allow the engine to produce more power and circumvent the above restrictions by stating that they are “for off road use only”.
