I'm replacing both 02 sensors in my 2000 Acura TL. I bought the OEM sensors made by Bosch however during installation I found out that the wires of both sensors were too short. Question: Are there extension wire specifically made for application? If none, my other alternative is simply to splice the new sensor wires with the original making sure I have good connection. Will this work?

sure, take the old sensor, and use those wires to extend the new sensor... i would make sure that the solder points are good and strong and use heat shrink tubing and some good electrical tape because that area will be exposed to road grime...

I went to see an Acura mechanic and I think this guy is pulling a fast one on me. I'm a fairly knowledgeable car mechanic myself (I think) and also one of my especialties before retirement is electrical and electronics. First this mechanic said that Bosch 02 sensors will not work. Instead he recommended I get the Japanese made 02 sensors (Denso, NGK or something). Second when I suggested that I do the splicing, he went to say that I should only use a specific type of connector. I have a collection of connectors and shrink and solder but he insisted I use his and for two hours of work he'll do the job for $148.00. I fully understand of the need to make a good connection as I'm dealing with a device which deals in low voltage and sensitive to changes in resistance. I intend to crimp it and then solder it plus the heat shrink. I also intend to install a cable protector although the area where the cable is secured two is pretty much on the fire wall. I've done some research and talked to other mechanics about the prudent need to replace the sensors at around 100K miles. this mechanic said no need to replace the after cat sensor. The concensus from other sources was that both should be changed. So what do you think?

Ive only changed sensors as they failed... and a good connection is a good conection no matter what you use to get it...

But do you know if the Bosch sensors are just as good as the original Japanese made (Denso) sensors?

I prefer Denso personally..
