Stillen G III intake..... WTF??

Jordo!

OEM filters are shielded within an airbox, with ducting to draw cool air from the bumper. It could be improved upon (with at least high flow panel filters and smoother intake tubes), but it a reasonably well designed intake system as is.

Short rams offer higher flowing cone filters, which improves airflow, but do not come with perfectly sealed airboxes, so there is some debate over their effectiveness without better heat shielding. In theory, using a short ram without an airbox means air temps will skyrocket at idle, although they will drop to ambient when moving. However, the constant heat up cool down may skew AFR corrections and possibly affect driveability (others may wish to chime in on this -- I have had this happen on other cars, but can't speak with authority as to whether or not this occurs with the Z).

The Stillen Gen III's (and similar) get around the heat shielding issue this by positioning the filters out from under the hood -- but, that also means there is at least some small risk for drawing in water (more so if the filters sit down by the wheels, obviously), which would be rather bad as water doesn't compress like air...

Anyway, an ideal aftermarket intake would have a CNC machined circular or oval bellmouth velocity stacks and highflow cone filters to improve airflow, excellent heat shielding, look and fit like OEM, and make use of the OEM ductwork to draw in cool air without any risk of hydrolock.

Still waiting on that.

Most intakes are simply pipes with a place to screw in the MAF and a cone filter... which is why I recommend smooth tubes and high flow panel filters as one of the best bang-for-the-buck mods.

Anyway, that said, I picked up a set of short rams that have nice velocity stacks, but I have to build fiberglass airboxes for them to get the most out of them... maybe over the summer.

This is where you gotta love being a part of the Z community, I was totally expecting to get ripped a new one lol and instead I get your magnificent response. Thanks for your two cents, much appreciated... As much as I see everyone going the stillen route I feel like it's not worth the money considering it seems like you have to remove the bumper to get to the filters... Any idea on the best smooth silicone or otherwise arms to get for the money? What I have seen seems a bit pricey for some simple tubes.. Keep us posted on your fiberglass boxes!

Having to remove your bumper should not be something the deters you from buying the G3 intake. I can have mine on the ground in under 10 mins.

Z1 Silicone Post-MAF Intake Hoses

I don't know if it's the best but I have no complaints with anything I've gotten from Z1

I have yet to mod my Z performance wise and haven't done anything too intrusive so I figured it was a bad idea because having done a few things to other newer cars I've noticed good old nuts and bolts are now substituted by crappy plastic clips that break easily but if you say it's no biggy... Thanks for the link z1 does look like the best bang for the buck too.

There's no real difference so long as they fit -- any will do.

Will definitely post if I ever get around to building the boxes, as well as dyno tests, IAT's, and such.
