You might think, "Wait a minute, I can get a genuine Bosch oxygen sensor from the other guys for a fraction of this price. What gives?" Don't be fooled. GoWesty is not trying to gouge anyone on oxygen sensors.
The other guys are selling "universal" splice-in type units. They are genuine Bosch, yes, and in fact we used to use them in our own shop. The difference is the other guys don't have a repair shop, and don't actually install what they sell. We do, and we have found that the three-wire splice in Bosch oxygen sensors don't work on 86-91 Vanagons, especially in wet conditions. Which is worse than if they never worked. If that were the case, you would know for sure the moment you put it in. But what happens is that you think you need an oxygen sensor because of certain symptoms, you replace it, it works, then it runs crappy again. Now you are "sure" it is not the oxygen sensor because, "Man, I just replaced it!" Time goes by and (you guessed it) no warranty on the one you bought. On top of that, you start replacing a bunch of other more expensive stuff trying to fix the problem.
Believe us, this more expensive, direct-fit, non-splice oxygen sensor is cheaper than what a less expensive, splice-in unit will cost you down the road. What's that saying again? Oh yeah, "There is never time to do it right, but always time to do it twice!" Be smart and do it once! These direct-fit oxygen sensors should eliminate any oxygen sensor related problems for 60,000 miles (please note, however, that they come equipped with our standard one-year warranty). This is not the area in which to try and save money!
