What are you hoping to accomplish with higher-flow injectors?
Contrary to popular belief, higher-flow injectors are not a performance upgrade. The only time they become necessary is when the air ratio overwhelms the stock injectors ability to compensate to reach the stoichmetric A/F mixture. This usually only happens as a result of forced-induction, or an absurd amount of nitrous.
The Cobra MAF on your car will most likely result in it running too lean. If you need a replacement stock MAF, try posting a WTB in the appropriate section, or search your local junkyards for the proper MAF.
