Frequently asked questions
Do I need a ProVent filter on my diesel?
While not factory-fitted, many diesel owners install a ProVent to protect against intake fouling and long-term performance loss. It’s especially recommended for turbocharged diesels with EGR systems, as it helps reduce soot and oil sludge that can block the intake and shorten component life.
How does this prevent "engine choking"?
Diesel engines recirculate soot via the EGR system. When this soot mixes with oily crankcase "blow-by," it creates a thick sludge that clogs the intake manifold. The ProVent removes 98% of the oil mist, ensuring only dry air and soot enter the intake, which prevents the sludge from forming.
ProVent Filters
ProVent filters are high-performance crankcase ventilation systems designed for modern diesel engines. They separate oil mist and blow-by gases from the crankcase breather before they reach the intake system. By removing these contaminants, ProVent filters help prevent carbon buildup, protect the turbocharger and intercooler, and keep your engine running more efficiently.
Why use a ProVent filter?
- Protects your engine – prevents oil deposits in the intake, intercooler and turbo.
- Improves reliability – reduces carbon buildup on intake valves and EGR systems.
- Maintains performance – ensures clean airflow for better efficiency and power.
- Universal fit – suitable for a wide range of turbo diesel vehicles.
