Hi, all !
Has anyone replaced injectors on a 2.4 ? If so did you go stock or aftermarket ? Also which brand ?

Thanks

Most go aftermarket, since they typically want bigger injectors to support increased power output.

The injectors from the LSJ (Cobalt SS/SC) work with the 2.4L connectors. The only thing that needs to be done is the fuel rail's bolt holes drilled/dremel'd out to accomodate the shorter length of the injectors. You want the fuel rail sits lower, basically.

Stock are around 24lb/hr flow rate. Stock LSJ injectors are 36lb and you can obtain them for around $30-50 over on the CobaltSS.net classifieds. You can also use their "stage" upgrade injectors, such as the 42lb/hr injectors that you can find on there in the classifieds for $100-150.

If you run the cobalt injectors will it make a diffrence if untuned?
