Not gonna get you much other than sound and a lighter wallet.

Factory set up is a (not extremely unrestricted) CAI anyway, and flows more air that a stock engine can use.

What are you basing that on?

Getting rid of the 3 resonators is what I was mostly interested in.

Go about a page or two into that thread. There are several variations shown, including ones that keep the stock air horn, like the one I did to mine.

Very nice. I was considering ABS as well. Nice work.

Basing what on? Looking at it shows it is a CAI, the intake is straight into the grill.

For the amount of air flow, there are assorted threads on the forum involving dyno trips and reading the computer parameters with fun software I don't have.

I'll accept dyno trip as evidence, but not looking at it and assuming. :)

As I posted elsewhere, I'm going to do some testing of the fuel economy changes (if any) when doing what Euchre did. I got the pieces tonight to do that same setup.

I had all three iterations, the stock set up, the PVC set up, and the Cosmo. The cosmo is tinny and loud and actually seems to rob some low end torque. The PVC set up was $10 and sounds the best. As has been mentioned, the stock system even with all the resonators flows PLENTY of air for these cars. Its pretty broadly accepted among the turbo guys that you really don't need an upgraded intake until you go with an upgraded turbo. So in stock N/A and Turbo cars a new intake is really simply a cosmetic or sound upgrade. You're in Portland, if you don't believe us, go down and talk to the Rallitek guys, they'll tell you the same thing.

Tinny with sound you mean?

As I think I posted, I got an OBD scanner that does fuel economy. I'll be doing my own testing and see what I come up with (if anything). :)

I can't imagine much of a gain at all. Fuel economy is my main goal.

These engines already have a high VE (volumetric efficiency). The intakes are designed for equal air flow to all cylinders and the intake tube is designed for smooth flow and temperature control. If you want colder air for density increases it won't happen. The stock intake tubing or an add on will still increase the air temp as it travels through the heated tubing. Plastic do keep the temperature down more than metals, so you definitely don't want metal tubing.

Noise levels from air flow will increase with removal of the resonators.
