Hi

can anyone tell me a definite yes or no if the 2 lambda sensors on the 02 Sti Prodrive are the same?

My front one has gone and I was going to swap them over and put a cheap 4 wire in the centre

thanks

Mark

You will also have to do a ecu reset once you have fitted the new sensor to change mine i took the collector pipe off the car heated collector up with blow torch whilst in a vice and undid lamba sensor as they are usually stuck fast , i also removed the headers whilst doing this and ported out the headers and collector to match the gasket size to help gas flow eg lowers spool up and increases torque .

Many thanks for the info

surely not two lamda,s one and the other one will be a cat on fire one i think a universal one will suffice,but apparently will not last as long but for £35 quid you can replace it a few times
