As above seen a few people with these injectors lately , and iknow msd do them , are these superior to the green and grey type injectors that im used to seeing ?

Im hopefully trying to get my car down to msd when theres a space with some mates etc , and wondered if this could be a way to go ? got light blues here which im selling and got the usual stage 3 set up a the moment greens/3 bar , just a bit of info or am i better off just sticking with what ie got

What siemens injectors are equivalant to my stage 3 set up

thankoo
