## Overview

The BOSCH 16978 Oxygen Sensor combines decades of industry-leading innovation with precision engineering. Featuring a double laser-welded stainless steel body, fast-acting heater, and direct-fit OE connectors, it ensures rapid sensor activation, long-lasting durability, and seamless installation. Compatible with select Audi and Volkswagen models, this sensor helps optimize engine performance, reduce emissions, and save fuel—making it the smart choice for discerning drivers who demand OEM quality without the dealer markup.

## Description

Every Bosch Oxygen Sensor benefits from the technological and manufacturing experience gained from decades of production, since first inventing the Oxygen Sensor in the late 1960's, ensuring long-lasting performance that you can count on. Bosch Oxygen Sensors are 100% tested for full functionality, resulting in a seared appearance of the protection tube, to ensure every Bosch manufactured sensor meets Bosch's rigorous standards for quality and performance. Exclusive double laser-welded stainless steel body is totally submersible and sealed tight to protect against damage from exhaust emissions - ensuring a longer sensor service life. Fast-acting heater optimizes sensor operation on Planar and 3, 4, and 5 wire Thimble type sensors allowing the oxygen sensor to reach its operating temperature quicker - within seconds - for optimum performance. True Direct-fit OE connectors and harnesses, along with threads pre-coated with anti-seize compound right out of the box, make installation simple and hassle-free. It's critical that oxygen sensors are replaced at the suggested intervals provided by vehicle manufacturers before the sensor fails. Following the recommendations will prevent long term damage to a vehicle's engine, reduce harmful carbon dioxide (CO2) emissions, and save money when refueling your vehicle.

Review: Easy install, and perfect fit. - I had an O2 sensor fault. The dealer wanted more than double for just the same sensor, so I decided to look around for an alternative. This part showed as being compatible with my 2003 Audi allroad 2.7T, in additional to several other makes/models. In case you were unaware, Bosch is the manufacturer of many of the VW/Audi parts, including O2 sensors. Upon initial inspection, I found the replacement to appear to be identical in both shape and construction as the original. It was easy to install, and simply worked. The kit comes with 2 different wiring harness housings. One of which is pre-installed. For my application, I had to swap out the housing to the other which was included. Unfortunately the included instructions do not show much about this part of the process. If you are not familiar with VW/Audi wiring housing, I strongly suggest searching for a how-to and/or video on how to remove the cable terminals from one housing and install them into another. It's not difficult, but does require the know-how, otherwise you can damage/break the housing and/or terminals. Summary: Item was compatible and worked flawlessly. Easy to install, with no fitment issues. This O2 replacement is identical in shape, appearance, function, and quality as the original, but at less than half the price you would pay at the dealer. Recommended!

### ⭐⭐⭐⭐⭐ Direct Fit / Replacement
*by N***Y on March 9, 2019*

I bought this for my 2002 Beetle Turbo S, downstream. It is an exact replacement, plug and play. The only issue is the cable/cord is much longer than what came on the car. It’s easily solved with a few tie straps however. There is an additional plug included in the box, maybe it’s ised for some other cars? For the Turbo S however, no cutting or splicing is required. Remove the two bolts in the band clamp that join the cat pipe and intermediate pipe. They’ll most likely break, go to Lowe’s and buy stainless steel to replace them. The cat pipe will drop enough to allow you to remove the sensor from the cat. I used a 7/8 line wrench and tapped it with a hammer. Easy peasy, lemon squeezey.
