Why not have your old ones cleaned and flow tested? There are a number of different places that do this, but I use a service called Cruzin Performance at www.cruzinperformance.com/.I need some insight on injectors. While I have my engine all torn apart, I want to replace injectors cause the have 132000 on them. But oem injectors at are over $1000. It's there another brand that someone has used or should I just go with bosch? Need so help here
