This Denso lambda sensor (OEM code RF7J) monitors exhaust oxygen levels to optimise the air-fuel mixture in your Mazda 6 (GG) 2.0 DI. Removed from a donor vehicle, the unit shows visible wear and surface rust on the body, so inspect fitment and connector condition carefully before installation. Verify OEM-code compatibility with your original sensor before ordering to ensure proper function.
