The issue with O2 sensors is not the length of the wires, but the distance the sensor is from the exhaust valve. If the sensors are too far away from the exhaust valve, they get too cool to work effectively. The hotter the O2 sensor, the better it works.
Extending the wiring is simple and the length of the wire is not critical. Be sure you have the right kind of wire. It gets very hot in the exhaust area, so high temp insulation is a must. Make a trip to Skycraft at I-4 & Fairbanks in Winter Park. You can't miss it, there is a flying saucer on top of the store -no joke, there really is a flying saucer on top. Ask for some 16 or 18 gauge Teflon insulated wire & some 1/8" heat shrink tubing. Get 8-10 ft of wire and the heat shrink comes in 1 ft or 3 ft lengths. The heat shrink tubing is a must to cover the solder joint splices.

You can simply re-route them with no cutting or soldering. If you trace them, you'll see they go all the way forward by the steering rack, then up to the top of the engine and back to the rear. If you unbundle them from their harnesses you can then simply run them down the back of the engine for all the length you'll need.
