In order to convert these gases, the catalyst of your Mercedes Classe M a mesh of precious metals which, when the gases pass at high temperature, will break them down by chemical reaction . A catalytic converter can only work from 400°, it is therefore necessary to avoid clogging the catalytic converter of your Mercedes Classe M. If you are thinking of making enough long journeys to heat it up regularly (count more than 10 kilometres for the catalyst to reach the right temperature), this will allow you to optimise the life of this part and preserve ideal engine unit effectiveness.
