Walker Products Engine Management and Oxygen/Air-Fuel sensors have been engineered and developed to be an Original Equipment Manufacturers replacement for many vehicles worldwide. Every part number is manufactured for the specific application, fitment position on the vehicle, and will provide the relevant diagnostic system feedback as required by the ECU. Newer vehicles will store fault codes in the ECU, some will relate to the affected sensor and its associated systems. A failed sensor might make itself known by causing the engine to run poorly, increase fuel consumption, exhaust emissions, or illuminating a (MIL) malfunction indicator light. The sensor, wiring harness, and connector should also be checked for physical damage. This will most likely also cause their operational life to be shortened. We are an Automotive ISO9001/TS 16949 certified company, with un-paralleled customer service, marketing, and shipping. Our electronic and paper catalogs are designed for today’s fast paced marketplace, along with our eye catching packaging. Since 1946, Walker Products has been the number one choice for the engine management sensors and fuel system components needed for your vehicle.Vehicle Fitment: 2006-2020Audi A3 Quattro 3.2LAudi A8 Quattro 3.0L6.0L6.3LAudi allroad 2.0LVolkswagen Beetle 2.0LVolkswagen CC 3.6LFord F-150 3.5LFord Focus 1.0LVolkswagen Golf 2.0LVolkswagen Jetta 2.0LPorsche Panamera 3.0L3.6L4.8LVolkswagen Passat 2.0L3.6LAudi A3 2.0LVolkswagen Phaeton 6.0LAudi Q5 2.0L3.0LAudi Q7 3.0L3.6LAudi R8 5.2LAudi S6 5.2LAudi S8 5.2LVolkswagen Touareg 3.0L3.6LAudi TT Quattro 3.2LAudi A4 Quattro 2.0LAudi A4 2.0LAudi A5 Quattro 2.0LAudi A5 2.0LAudi A6 Quattro 2.0L3.0LAudi A6 2.0LAudi A7 Quattro 3.0L
