I did this about a year ago actually. It all started when my friend had some different aluminum intake pipe pieces purchased from Ebay and he gave me one with this simple bend in it. Off with the factory setup and then I began mocking up the pipe, cut it to fit, then drilled a hole for the intake air temp sensor (IAT) and painted the pipe with some two-stage silver I had. I used a PCV grommet from Advance Auto Parts for a couple bucks that the IAT fit into and then went to the local hardware store to find the rubber coupler because the throttle body is 3 1/2'' or so (don't quite remember) and the intake pipe was about 3''. Then I went to www.KNFilters.com and went through all of their custom fit filters to find the one that would work the best. It's a oval-cone shaped one and instead of the end being capped with their usual chrome cap, I got one with the "Xtreme" top so air could enter through the front.

Overall, I can't say I've really gained anything as far as fuel economy because my driving varies all the time and of course, I really didn't feel any increase in power (I don't think anybody can feel a few horsepower difference) but you can certainly hear the intake a lot louder now...and thats not a bad thing either because it's only at wide open or close to it when you really hear it. I also added in a picture of my painted intake, valvecovers, fuel rail cover, etc. Painted again with GM Ultra Silver over two years ago and still holding up, what do you think? Thanks

Looks great!
but your still sucking in hot air from under the hood.

I would understand some hot air, but there is still the inlet tube in the core support that directs air from under/behind the headlight that fed the stock air intake.

There were discussions of these intakes couple of years ago on an Olds forum. Seems one of the fellows dynoed his 3.1 Custom Supreme with the cone setup and with the stock airbox. The stock came out ahead. He opined that while simple logic dictates that the freer breating cone should increase performance, sound and psychology aside, all the engineering that goes into the stock box results in the correct turbulence and air speed for the engine. Not sure if that holds true for our 3.8s as well.

I don't doubt that one bit! lol because like I said, I didn't notice anything, even though such little improvement, if any would be hard to feel. And the stock airbox in these E-bodies enclose the filter to keep the air cooler, I would assume. Ah who knows, the world may never know! Just thought I would hear some feedback!
