Mixing injectors IS NOT a good idea..
You can get inj. on ebay for around 50.00 each..
OR replace the nozzle yourself.. for about 25.00.
You wanna stay original.. there is NO WAY to tell from looking at the nozzle, whatcha got..
There is a # stamped on the injector body that tells whats inside it[nozzle].. just below the return..
