Good stuff. Just ordered both, but manifold on backorder 6-8 weeks of course.

Does anyone know a source for the injector spacers in Canada? MMX are smoking crack with their shipping rates. Otherwise I'll have to tune for the 6.4 injectors I guess

No. your truck should already have it
So the active runners will automatically open and close without any additional parts or tuning? Do you know if the controller is native to the intake manifold or if the pcm is sending a signal to open or close? Because the 5.7 manifold doesn't come with active runners right? So there must be a passive controller on the 6.4 manifold activating the runners based on RPMs or something it is reading from the PCM?

Factory 5.7 has active runners , you just need an extension harness or make longer yourself. The 5.7 is in the rear and 6.4 in the front .

Finally found a 6.4 (truck) intake manifold for a good price on ebay. Also picked the AF Dynamics cold air intake. Curious if anybody knows where the IAT sensor will plug in and if I'll need to make an extension for it?
