These injectors are usually used on Volvo R engines, I used them to upgrade my C70 2.4T adjusted my ECU tune and everything was spot on. Have to always buy genuine with injectors which these are you will see the Bosch symble stamped on it rather than a blank circle. These are the most copied injector out there and fake injectors can have such difference in flow between them it most likely would cause engine damage. All 5 of these from Automotove super store where bang on to the ml and couldnt expect less from genuine bosch.
