All NGK/NTK Oxygen Sensors are platinum coated for durability and are individually tested to guarantee quality. You can be assured the NTK oxygen sensor for your car will install as quickly and plug in exactly as if you bought it from the dealer, as NTK is the worlds leading supplier of OEM oxygen sensors and supplies more vehicles manufacturers with oxygen sensors than any other company.  Also keep in mind that when the plenum cover gasket leaks it causes oil to be drawn into the intake manifold. This causes increased oil usage, smoking, pinging and power loss. The additional oil usage will cause excessive carbon to build up on the oxygen sensor. The carbon acts as an insulator effecting the operation of the sensor which controls the power, mileage and emissions. We suggest you install a new pre-catalytic (front) O2 sensor when replacing the plenum cover and gasket.
