Hi, I have an APY s3 which only requires 1 Lambda Sensor (pre cat). Im trying to shop around to find the best deal on a new unit. My local Auto Factors can supply me with the required part for about Â£40, the only issue is this is a Febi part and not a bosch. My local TPS have Quoted me Â£120 for a new bosch unit (part number 02580060332). My questions is: is it essential that i buy a bosch unit over the Febi part? does any1 have any views on this please?
