Question about 42lb/47lb injectors

[JustinReed]

I'm pretty sure I'm set on getting the Cobra Jet intake manifold, are there any negative issues with also adding the 42lb or 47lb injectors? Is it worth adding either the 42 or 47? Or just keep the stock injectors?

Any info is greatly appreciated!

Unless going to E85 there is no benefit. If E85 with a manifold swap then you will need injectors. 47's ftw.

I will be going with a flex-fuel tune, either Lund or Livernois. Once I do more research, I'll see which one has a better tune.

Thanks for the info.

The throttle response alone from stock injectors compared to the 47lbs injectors with an upgraded manifold are worth the swap on pump gas. Being able to run E-85 is just an added bonus.

Go with the 47's

LU47 ftw.

go with Ford Performance LU47's and AED for your tune.

+1 for the AED tune and injectors
