High quality EGR valve adapter / replacement.When you notice that your car has lost its former power, jerks when accelerating and smokes, the EGR valve is probably the culprit. The cause of the mechanical failure of the EGR is the deposition of carbon deposits inside the valve, which increases its resistance during operation. It does not react quickly enough to pressing the gas. Carbon deposits also build up at the valve face and can be kept open despite an increase in engine speed. The EGR valve is plugged to prevent exhaust gases from entering the intake manifold. As a result, the above-mentioned signals indicating damage to the EGR valve often disappear, and the car returns to the time before the failure. Parts made with CNC laser cutters lose the properties of the material from which they are made, due to the increase in temperature at the place of the cut. & Nbsp
