Catch cans – also known as a crank case vapor oil separator – are a key aftermarket component in your engine’s crankcase ventilation system, standard OEM Petrol and Diesel vehicles don’t come fitted with a catch can and the OEM oil separation is very poor, leading to progressive and performance robbing buildups inside your engine and components like intercoolers, intake manifolds, valves and turbo chargers. BossVent is designed to filter out blow-by oil and keep your intake system clean & healthy while constantly keeping watch on catch can oil level and filter blockage status.

If a catch can filter slowly becomes blocked it can increase crankcase internal pressures and lead to engine oil leakage, or the catch can simply bypasses allowing the oil it’s meant to filter out to coat downstream components such as intercoolers, intake manifolds or turbos all without you knowing.

BossVent prevents this by continually monitoring the status of filter blockage and catch can oil level, alerting you when catch can maintenance is required before it leads to potentially costly engine damage.
