Part number:1 Item Weight:100 g Package Dimensions:14 x 11.5 x 2.3 cm; 100 Grams Style:Modern Material:Alloy Steel Plug profile:Flange Mount Specific uses:Oxygen Sensor Included components:NO Batteries included?:No Batteries Required?:No O2 Sensor Adapter,2Pcs Oxygen Sensor Spacer Extender O2 Sensor Bung Extender Isolator for Exhaust Systems with M18 x 1.5 Sensor Holes Check Engine Light fix is basically a way to space out the O2 sensor so that it still reads SOME exhaust gasses but it removes the O2 sensor from the direct flow of the gasses as to make the ECU believe there is a restriction in the exhaust gasses such as by a Catalytic Converter. Features: *Made from high-grade NICKEL plated steel *It adopts surface plating treatment, which is rust-proof, and hexagon design brings easy installation. *Simply threads into the existing bung *The length of the O2 sensor adapter is 4.5cm and the diameter is 1.5cm. *O2 sensor adapter M18 x 1.5 Anti-crack Durable Thread Adapter for most cars. Specifications: Name: O2 sensor adapter Material: Iron Color: Silver Thread Size: M18*1.5 Length: 45mm/1.8inch Hex: 22mm/0.9inch Item Quantity: 2 Pcs Package Weight: approx.100g/3.5oz Package included: 2 * O2 sensor adapter About this item Selected Permium materialsOur O2 sensor adapter is made of high quality steel and is precisely processed. They have the characteristics of high strength, burn resistance, corrosion resistance, dense and uniform structure, and good corrosion resistance. They are durable and have guaranteed quality. Electroplating processingThe surface of this O2 sensor adapter is electroplated to form a smooth surface, which can effectively prevent rust. High precision and small tolerances provide you with excellent results. Excellent performanceThe O2 sensor adapter is a special tool for checking engine lights and repairing M18*1.5 sensor vulnerabilities, which can effectively increase the distance between the oxygen sensor and the exhaust system. Easy to UseThe hexagonal shape O2 sensor adapter is easier to install, just screw it into upstream and downstream O2 sensor adapter and car exhaust pipes without modification Wide application rangeO2 sensor adapter has a thread of M18 x 1.5 mm,this O2 sensor adapter can be used in most modern automobiles, It fits most O2 sensor threaded sockets or tools.
