The Lamda looks to be an M12. Whats the correct size for a cossie before I go make any other changes?!!
Standard Saph 4x4 and BT Escos lambda is M12 fine not M18 fine.
Just fitted a down pipe on mine and had to bung the M18 as the new turbo has a lambda port thats M12 and thats where I fitted mine - Saph 4x4
