NTK EGR Valve EGE5-D015 (NGK94508)

Nitrogen oxides (NOx) are produced during the combustion process. NOx is created when high combustion temperatures enable the nitrogen and oxygen present in the air-fuel mixture to combine. To reduce these harmful emissions the EGR valve takes exhaust gases from the exhaust manifold and reintroduces them into the intake manifold, mixing them with fresh air. This has a double effect, reducing the amount of oxygen in the air-fuel mixture and reducing the temperature, and thereby reducing the amount of NOx the engine produces

To ensure the high, OE spec quality you're used to from NGK products, all EGR valve products from NGK have undergone and passed testing carried out in extreme conditions. This includes thermal shock testing in temperatures ranging from -40°C to 150°C, tests on valve, cavity and cooling leakage, as well as electrical resistance and lifecycle.
