BOSCH 15730 Premium Universal Fit Oxygen Sensor - Compatible with Select Acura, Audi, Buick, Cadillac, Chevrolet, Dodge, GMC, Honda, Hyundai, Infiniti, Jaguar, Jeep, Kia, Mazda, Nissan, Subaru + More

used this unit to replace the OEM sensor on 05 Miata. Original part came out much easier than I expected. I soaked the original sensor with PB Blaster about an hour before I tried to remove. The original sensor came right out with not difficulty. Pay attention to the wiring chart is not very intuitive as the color code on the part does not match the factory wiring. Two of the wires are used for the "heater" and the other two are the actual sensor. The supplied wiring connector works well. I moved the connector to a location high in the engine bay to keep it better protected from the elements and make it easier to reach in the future. I also added additional never-seize to the threads to insure easy removal should it ever need to be replaced.

Easy to use and install. Comes with step by step picture installation guide. It guides you through measuring the length and where to cut the wires, although I would double check your measurements and see if it'll fit properly. Mine could have used an extra 10cm for wiggle room.The installation guide also comes with a wire colour code chart to convert your OEM wire colours to the Bosch colours.The plug is a little fidgety but fairly simple to put together with the picture guide. It's solid and weather proof. The four twist-lock/clamping connectors are extremely solid (they're way better than crimp terminals) The yellow circle rubber seals the back of each connector and then then large shields go on top.The sensor itself comes pre-greased which is super handy.I'd buy this again.

During my inquiry I read the Q&A where the seller assured customer that his universal sensor should work. I bought it and installed correctly to instructions. IT DOES NOT WORK. I called Bosch and a technician from there called me back a few hours later to inform me that no universal application exists for my Subaru Baja and I simply had to order the correct 15501 unit I did from a local parts distributor and it works as desired. I feel cheated out of my time and money in this process. If you don't have the answers for application don't make something up and for Heaven's sake don't lie about what vehicles "it should work in". The installation (as required in Universals) requires cutting the lead wires to length matching the existing sensor precisely. This action voids the ability to return the sensor because the wires are cut. Convenient way to unload stock and avoid returns. Quite clever.

It worked, my Check engine light is still on but it's no longer the bank 2 converter code. The converter is probably dead. But the rear O2 sensor was original and 12 years old, it was shot.Anyway, putting this thing together takes patience. It's not that hard, just annoying and you can't really rush. In addition, the poster that said leave a little extra wire was correct if you follow the instructions, you get to put the connectors on inside the plastic connector box which is impossible.The instructions could be better. If you hate building models, you'll hate this, if you like building models, you'll get an extra treat and fix your car.I later found the non universal sensor at another mail order place for the same price, if I had seen it first, I would not have bought this. I don't enjoy building models. Look around and see if you can find a non universal sensor first for a similar price. If you can't you'll get to build this too.I can't speak for the longevity of this thing....

Received this item sooner than I expected, bought this for my 1997 Dodge Gran Caravan because the check engine light came on.I have been unplug the negative battery terminal to get around the smog check but not this year, the ODB 2 code reader showing P0140 which is the downstream O2 sensor.You will need a special tool a 7/8" long socket with slot cut in the side to remove the old sensor, I went to auto part store got a loaner tool for this week end job. The instruction comes with the new part was easy to follow and no more error code when I scan it again. The whole job will take about an hour if you have the right tools.I read on all the reviews before I purchased this part, This O2 sensor is for "downstream".

This product worked - but it was a lot harder than it had to be. When you see universal read pain-in-the-butt. You have a bunch of splicing and connecting of wires to do. This job would have been so easy if I could have just plugged a new one in. If you can find one that will fit straight into your machine I would recommend doing so. If not just be ready to do some work. Also, I recommend saving a little more wire than they tell you to - just gives you a more to work with.Best of luck!

works well...install was easy to me...my stepdad was helping me and he was unsure of the 'twist and lock' option for the wiring. he wanted the wires soldered, but when I noted that the instructions clearly stated that soldering may shorten the life of the 02 sensor, he begrudginly allowed me to install the unit per the instructions.I installed this in my '03 accord coupe. The only thing that I would suggest is pay attention to where you want the 'swist and lock' wiring block to be placed (which will be determined by how long or short you make the wires before installation). I opted to route them such that the block was close to one of the factory wiring looms and in a spot where the catalytic converters heat sheild was protecting the wiring block from the heat of the cat.

Front sensor replacement for '02 Miata fed spec (and most years). Splice it yourself budget friendly so there is a little work to be done cutting the connector from the old sensor and using the twist lock splice connectors from Bosch. Just need care lining up wires per instructions. Lasts the usual 50k+ mi the prewired more $ ones do. I believe 15740 is just a longer wire version for downstream (I've used it there with no issues on same car).
