CAIs do not fit with the supercharger. I'm pretty sure it is because there is absolutely no room left in the engine bay once the supercharger is installed.

it's not only the room that's a problem, but the supercharger is directly in the path from the intake piping and the intake manifold. Also, the way the supercharger is designed changes everything. From the airbox, there is a short U-tube going to the S/C, then another hose from the S/C to the intake manifold. The only aftermarket intake available right now that fits without modification is the Umnitza carbon fiber one. Only problem I've heard with the Umnitza (and modified aftermarket) intakes is if you use it with the S/C, you may have problems with the engine running lean.

i should take that pic again but put the intake in it. THERE IS NO ROOM. When ZPI come out with theirs its going to be interesting to see how the bends are.


(oh and on a side note. I looked today and the BPV is in the top of this pic. Can it be replaced without taking out my DC sports strut bar?)

Relocate the battery, and remove that intake cap. A lot can be done.

Nope. I had to take my DC Sports strut bar off to install the bpv. It makes it a whole lot easier

I've seen someone take their aftermarket intake and cut the tube right before the MAF sensor bung and make a short ram intake. They attached the intake to the stock rubber tube that comes with the supercharger. Shouldn't be too hard to do a CAI, just need to figure out how to mount the piping.

I'm wondering the same thing. I've seen a bunch of intake posts being moved to F/I and now we have a S/C question being moved to NA. Weird I tell ya.

have anyone thought about extending the tube and place the air filter for the S/C where the Air Filter would be if it were a CAI?

Too many people argue that having a CAI isnt beneficial since air passing thru the turbine turbo or sc will be pressurized and heated.

Ive done replacing the stock airbox using aftermarket MAF adapter tubes but i dint like the way ti drives on the low end. nice gain tho on top end.
