Hi all, Looking to replace Lambda sensors(both of them). According to RealOEM.com i only need one (SIEMENS/L=990MM Part no. 11781427884) although I'm positive i have two!

I can get my hands to two from am M3 Evo... see below

BOSCH/L=1145MM Part no. 11 78 1 404 696 & BOSCH/L=1005MM Part no. 11 78 1 404 697

This maybe a silly question, will these work on my 323i (m52)?? they are obviously longer, but maybe that is the only difference??????:confused

Hi there, this might help, follow the link and it takes you to ngk's part finder, if you pick the two different cars and compare the part numbers it might help

You will only have one, a pre cat sensor. euros or gsf have them cheap enough and they will be plug and play

Do i have one? do i have two? can some one explain?? Will M3 lambda sensors have the same fitmet?

you have two one in each manifold - one for the front 3 cyls and one for the rear 3 cyls same as a 328

None near the cat
