93 Landcruiser O2 Sensors

[adambattag]

can anybody tell me exactly where the oxygen sensors are on my 93 landcruiser, what i can expect when replacing them myself, and if aftermarket oxygen sensors are as good as the dealers?? Thanks

Dont know the Land Cruiser specifically but O2 sensors are normally low down on the exhaust manifold (header) or in the down pipe before the catalytic converter. If you have a secondary sensor it will be sticking out of the exhaust pipe just after the cat. Expect removal to be tough as it will probably be corroded in place. You should have no problem using generic aftermarket sensors and they are certainly much cheaper (at least they are here in the UK) they come in well under half price. Generally the only down side is that they dont come with the factory connector, so you need to do a little re-wiring to make the connections.
