1Oil Collector: You can install an oil collection can with a breathable filter for use in a PCV front car as a ventilation system, or without a breathable filter between the PCV hoses as a sealed tank. 2Convenient Design: The oil can has a low-micron bronze filter and a larger baffle. The bronze filter can better filter all kinds of fine impurities. The large baffle in the oil tank can cool the hot oil vapor over a larger area, turn it into a liquid and capture more oil. 3Filter Oil Can: Filter oil catch can, which allows air to escape freely while retaining oil. The baffle system in the fuel tank can also filter the air, reducing the amount of oil and gas entering the intake system. 4Lightweight and Durable: It can extend engine life. The hose, clamp and mounting bracket are made of aluminum, which is lightweight and durable. 5Applicable Models: Do not use filters on the PCV system, as this will only break the vacuum and cause engine problems. The filter is suitable for cars before PCV.
