Injector dalema

[kal2005]

Hey guys, so I blew out my cyl 1 and 7 injector so I am replacing the whole injector bank and I am wondering if I want to go with an aftermarket injector would I have to change them all or be okay with one bank and leaving the other side stock until they blow? Thanks for any help in advance

You need to keep the injectors all the same size or you'll be running rough and throwing contribution codes. I would just replace the two bad ones, the others may go another 100k. Make sure it's not your FICM causing problems, odd for both injectors to fail at the same time. Also make sure you have good fuel pressure since that can wipe out injectors.
