Hella Camshaft Adjustment Control Valve (6NW 358 188-121)

This Hella Camshaft Adjustment Control Valve is supplied in OE matching quality.

Camshaft adjustment control valves are used in variable valve timing systems to improve fuel economy by controlling the air and fuel mixture that enters the engine and lets the exhaust escape. The adjustment valve alters the opening times of the valves to cope with different operating conditions, depending on the vehicle's needs. This allows for optimal charge cycles within a range of engine speeds and loads.

Another great benefit of a camshaft adjustment valve is improved fuel efficiency, a reduction in harmful emissions, and an increase in torque and performance. So with a range of responsibilities and improvements, it's vital to ensure your vehicle's camshaft adjustment control valve is made to a precise fit and manufactured with high-quality, durable materials.

When you select original parts with the Hella label, you know that functional safety, a perfect fit, and product durability are guaranteed.
