I changed out my spark plugs yesterday, and while I was in there I figured I'd check the air filter. Well, one of the screws was stuck, and voila, I tore the threads. I've seen pictures of Aveos with cone-shaped air filters, and I checked out a few of the how-to threads on the board. Has anyone stumbled on any new ideas? I'd love to get rid of that plastic box. Thanks!

there is a cold air intake on ebay for $38.99 (i think) plus shipping. gives you the pipes, connectors and filter.
fitment might not be perfect. but its a good basis to start with for a small investment. i have heard people with A/C might have issues with them though? but i do not have A/C and have not purchased one yet because i was afraid it would cause cold air surging in winter and take longer to warm up the car when it is 10 degrees out
or you can just put a cone filter on to the stock pipe after removing the box
may the schwartz be with you!!
And also with you!
Im still working on my improved air box setup....schools holding me down right now with tons of work, but as soon as I get the time I got to take the final measurements and put it together.
I took a 2 inch long peace of 3 inch pipe and used it as a spacer between the stock rubber intake tube and a new aftermarket air filter. Which let me remove the entire plastic air box.
please tell me the 4" exhaust in your sig is a joke
Whatever you do...
DO NOT GET A CHEAP AIR FILTER, IT WILL NOT FILTER OUT THE MICRO PARTICLES FLOATING AROUND, AS A RESULT, A LAYER OF BLACK SOOT WILL FORM EVERYWHERE ON THE INSIDE OF YOUR ENGINE AND DESTROY POWER AND ECONOMY...
That's personal experience from me, I got my engine checked out and they took the top of the engine off and soot was everywhere on the headers, cylinders, everywhere...
every engine will be dirty when it is torn down. Cheap or expensive, high performance air filters have bigger orfices to let in more dirt.
AND i might add you want to get the largest air filter you can find. Why, the more filter area you have the easier your engine can breathe. If you get one of those tiny cones the surface area can be smaller than the stock filter thus reducing your available intake.
Just make sure it's not TOO big or you may risk going a little lean (sure not enough to ping, but enough to effect power)Quote:

And FWIW, leaner will always get you more power. There is a point that it becomes unsafe but theoretically, if the engine can take it, the leaner it is, the more power it will make.
I had my car on the dyno, I loss with a larger filter. I switched and got a small amount back and the a/f ratio changed. Plus leaner does not mean more power, you can have all the air you want but without fuel to support it you'll either go boom or not make what you are capable of.Quote:

This is a video of me installing and then driving the car with the AEM cold air installed. At the time of the video it was the only mod on the car. Turn up the volume to hear how good it makes the engine sound!

I do agree that you will go boom with not enough fuel. But from personal experience tuning cars, the leaner you make it, the more power it will make. I have seen cars gain upwards of 15hp just from leaning it out from 11-1 to 12.5-1
One was a K&N big cone used, the other was that crappy Apex or whatever from AutoZone new. The Apex made more power even though the K&N was cleaned before. Apex was used first. I do agree that there could have been outside influences such as temp change or heat soaking that I may not remember (it's been about 2 years at least)Quote:
