1. Product material: aluminum alloy. 2. Function: Collect steam in the crankcase, reduce the amount of steam entering the intake manifold, reduce the rate of secondary combustion, reduce carbon deposits, protect the engine. 3. Installation: The round oil ventilating pot is installed on the original vehicle exhaust pipe, collecting waste oil to protect the engine, reducing the carbon deposit in the engine compartment to extend the engine life! Before installation, you must first select the installation location. Since the engine will dissipate heat while working, try to install the oil ventilating pot away from the heat source to facilitate the cleaning of the oil-water mixture in the ventilated kettle. When connecting, be sure to fix it with a clamp and try to keep the whole pipeline in a vacuum state.
