these seem ok, spray patterns not too bad for a large injector.
i've run several of these on our asnu injector test bench, along side many others. they're ok.. not best in class atomisation from what i've compared against, but for their delivery duty vs atomisation vs spray pattern is better than may. Often seeing these rebranded by many folks , who also just rub off their last 3 digits to hide their heritage.
there are adaptors which clip onto the end of the long nozzle to allow oe fitment again, but i have'nt found any for sale seperate to the injectors, so am getting a batch of 40 machined & anodised to use.
