i assume you are talking about something like this:
http://cgi.ebay.com/ebaymotors/2002-03-04-05-TRAILBLAZER-ENVOY-BRAVADA-4-2L-AIR-INTAKE_W0QQcmdZViewItemQQ_trkparmsZ72Q3a1171Q7c66Q3a2Q7c65Q3a12Q7c39Q3a1Q7c240Q3a1318Q7c301Q3a1Q7c293Q3a1Q7c294Q3a50QQ_trksidZp3286Q2ec0Q2em14QQhashZitem56312c764aQQitemZ370192184906QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories

they do not remove the air resonator. they only replace the tube part. so it is going to very very very little if any for you truck.
dont do it they are a scam.

all the resonator really does is keep it quiet. So, if it is noticeable sounds that you want, you'll need to go to an auto parts store and buy a length of extension tubing. Otherwise, it is comparable. The metal tube doesn't dissipate heat as well as plastic, and I would recommend that you reuse/ modify the stock airbox, but I am happy with mine and did motice a difference in performance.

i just bought one of the cheap intakes, and it is coming next week. and someone said, this 'kit' does not require to take the air resonator off and if you leave it on, the intake is pointless... how do i/what do i need to get from auto zone to delete the resonator and make it loud and work well?

i got one from chromeintakes also. love it. did the gutt out air box mod too. but i also took off the resonator and bought a bypass tube from autozone and 2 clamps. sounds nice when i hit the rpm to 4k. worth the 30 bucks from ebay.

May be a stupid question, but how do the sensors connect? I believe there is a MAF sensor in the stock plastic tube, but I'm not seeing anywhere to mount them in the chromeintake part.

Trailvoys didn't get MAF sensors until after my year, so that's an IAT sensor. The vendor should have given you provision to install it, or you got it so cheaply that you have to drill and fab a mount yourself.

edward93: What's your code?

IAT sensor = Intake Air Temp???

I didn't buy a knock off air intake yet, but am considering it. I'm not looking for performance as much as fuel economy. I've cleaned throttle body, replced air filter, plugs and gas filter, and I'm still lucky if I get 15 mpg mixed driving. I'm hoping that a new, somewhat less restrictive intake will help a bit.

Contrary to the claims, an intake isn't going to substantially alter your fuel economy by itself. You'll get slightly more air into the cylinders, which the PCM will accomodate by adding a touch more fuel to achieve the correct clean burn. Depending upon driving habits, it could potentially lower fuel economy.

The ONLY two modifications that I've found to measurably help fuel economy and performance were a TUNE and and combination of an intake/exhaust. Engines are big air pumps, reduce the restriction in/out and it helps them move more air. (But more air = more fuel, so it really doesn't affect mileage much). A tune tweaks the fuel for bettery efficiency and adds timing, which in turn raises static compression, making more power for the same amount of air and fuel......translation better mileage if you don't constantly use it. (If you lead food around and race off every light, it will obviously be counter productive).

Ebay intake differences from 03-05, then 06 and above..

New to the site.. Need a little advice/help

--------------------------------------------------------------------------------

Nice DIY!!

I notice you dont have a MAF.. the problem Im having is I have searched around on here about the ebay intake etc but havent seen anything on how any member placed a hole for the MAF to insert in the intake tube..

I ordered the ebay intake last week, just got it in.. Now all I have is a chrome intake pipe, filter, 1in filter, clamps etc, and 2 braces..

The pipe has about a 1in circular hole.. WTF is that for? How does that help me? The MAF is rectangular, so do I need to dremel my own hole in the intake?

Do you recommend placing another gasket on the intake as well??


I see 05 and below probably have an IAT sensor and not a MAF sensor.. So I have to probably dremel the shape outta the intake?

If I dont get a response Im going to make a better thread on the Ebay intake for DIY, because its not as simple for 06 models with a huge MAF...

So ive been poking around on ebay lately and i found a kit on there that looks like the kit posted earlier except for the fact that in the picture the resonator is definately REMOVED. I believe the kit was like 80 bucks which is still waaaaay cheaper than k&n or others. My question i guess is has anybody seen or used one of these and also sound wise how much louder will it really be without the resonator. I dont really want it A LOT louder but a noticeable sound would be fine. I also plan on doing like a 50 series flowmaster. I want to have my trailblazer sound as close as i can to my full size chevy truck with flowmaster 40 series rumble. Any advise would be awesome!:thx

they make 2 different kits. 1 that bolts to the resonator box and the 2nd that bolts to the actual throttle body.

Yea i have seen both kits. But im just curious as to how much louder the truck will be with the resonator out of it. I dont want it too too loud because i will be putting a 50 series muffler on it soon.
