I must be getting old... :-) DIY 2012 intake modification

[TboneZX3]

What is the advantage of drilling the holes in the side of the box? Is the intake still restricted, even with the newmission mod? I would think these custom holes would pull in warm/hot air when the car is stopped.

It also seems it would drastically hurt the intake pull through the tubes.

Wife says it's a little loud=>the noise is just about perfect

The holes are in the area behind the headlight, so not exactly in the engine compartment. I drilled holes instead of cutting out a rectangular section so that I could tape up one(or all) if it was too loud or if I felt it hurt anything. I also have the spare airbox, so I can compare the effects of the two setups by driving each over time.

I'm gonna dyno it with the OEM airbox, then swap in the modded one, then do my exhaust.

First pull is windows up, second is not

By drilling the holes in the airbox..you completely made the ram air hose useless

The other 2 tubes that are attached to the airbox didn't seem to hurt the big tube from depositing large leaves and candy wrappers onto the filter before the new holes were bored. I haven't opened it up again since I modded the mod.

ie. the box was never sealed or relying only on the 3in tube for 100% airflow.

What are you doing for our hobby?

I see where you're coming from. I guess my concern would not be what is being forced ("rammed") through the newmission tube, but rather that the holes would reduce the amount of vacuum through the factory (cool air) tubes to nearly nothing. Granted, with the large newmisison tube, vacuum would likely be fairly low through the factory tubes already, but with the new holes I'm guessing it might be close to nonexistant.

Reducing the vacuum through the factory tubes and newmission tube and replacing it with air from the engine bay could raise intake temperature while at a stop.
