Hey guys, I need to extend my O2 sensors. I dont want to pay 40 bucks for the extensions. I heard something about not extending the wires because of the resistance in the wires or something? Is this true? Or can I just solder a longer wire in?
Extending O2 Sensors

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.
Thanks guys, I will try to re-route them as I have a lot of space right now and should be able to accomplish it, I was under there earlier and realized the harness was tied together with the oil lever sensor wire but I'll see if I can separate everything and clean it up again, if not I will do what you said Joe, I've been to skycraft a couple times, I love that place. You always find stuff you didnt even know you needed out there. I got my 80amp relay for my fan from there for 5 bucks.
