The JEC's MAF has different voltage scaling for the airflow and so will perform worse on the stock ECU. It also is not a performance upgrade, unless you are pushing more airflow than the stock MAF can handle, which you won't be doing on stock injectors.

As for the Diamond coil pack, it works fine and puts out higher voltage. I personally noticed no difference when I put it on, but they're dirt cheap and plug-n-play so there's no reason not to.
