i sold a set of gtr injectors for 350 a few months ago and these are better flow more and don't need a resistor pack, i bought them only six months or so ago for 370, clean and flow is around 30$ each injector if you walk in off the street. they have the tooth filled down so stock plugs fit and have a fuel rail so you can drill a beez dick to fit these injectors so for around 370 $ it's good value.
