Replacement Oxygen Sensor

The Replacement oxygen sensor is manufactured with attention to all the right details. This unit comes with a stainless steel shell shield and hex nut. The insulated wires are Teflon covered and the internal and external seals are made using high-temp rubber. Anti-seize compound is used to coat the threaded tube. With high-quality materials and special designs and features, this heated sensor provides top performance that lasts for a long time. The universal, 4-wire sensor, with 5.91-in. wire length, can help regulate both fuel and ignition systems, resulting in reduced harmful emissions, better fuel economy, and extended catalyst life. This sensor had been tested for quality and reliability. Complete with butt-type connectors and with threaded-in mounting style, the unit can be a perfect match for screw-in type bungs. However, this has to be installed with minor modifications if not compatible with flanges. This unit is offered with a 1-year, unlimited mileage warranty.

Bosch Oxygen Sensor

With this 4-wire Bosch oxygen sensor, engine performance can be greatly improved. The sensor, with a wire length of 27.2 in., can measure the air-fuel ratio in the engine with greater accuracy and efficiency. By feeding the engine computer with this data, the engine is able to run with less emissions and more efficiency. Built in a planar design, the sensor can provide the much-needed function and ensure reliable performance for years to come. With a highly functional oxygen sensor, premature catalytic converter failure can be prevented. The sensor features a submersible patented connection system; it won't get contaminated easily and will survive the harsh effects of engine vibrations and extreme temperatures. The wire can also be adjusted instantly, thanks to posi-lock connectors that make it easier to reconnect and unscrew. Wire splicing is required when installing the sensor. With a 12-month or unlimited mileage limited warranty, this part offers great value for money.

Denso Oxygen Sensor

The 4-wire, non-flanged Denso oxygen sensor is constructed to the highest standards using premium-grade materials. The sensor features double protection layer and aluminum oxide trap layer. It's also designed with a porous PTFE filter and stainless steel housing. Equipped with 11.77-in. lead wire, the unit is built to match OE standards. It was also subjected to performance and safety tests to guarantee premium quality and performance. With this sensor, the old connector can be reused. However, for installation, wire splicing and electrical mounting are needed. This product is sold with a 12-month limited warranty, so you can be sure it won't break down easily.
