I have a 2005 Trailblazer with a 4.2L engine. Why does the air intake assembly have two inlets going in to the top of the air filter cover? Prior to the air filter there are two inlets with one going to the air filter chamber and one going to the air filter cover. The other inlet going into the air filter cover is located between the air filter and the engine. Isn't there a chance dirt will enter the engine since there is no filter on the inlet going into the air filter cover between the air filter and the engine?

Ernie,

 

I see this is your first post. Welcome to the forum.

 

Not exactly sure what GM Tech4 is telling you here. Maybe he is joking with you and will come back with an explanation. I am not a Tech but I wish I could take a look at a Trailblazer to see exactly what you are talking about.

my explanation is that it is a question that should not be here for a tech to answer,the air filter design has to be ok or engines would be piling up,he does not understand is all,the engine is filtered period,end this nonsence.

Robert, I just saw this was his first post to the forum and possibly he is not what is called a "car guy". He was curious as to how the air intake worked and simply asked a question. I would not classify this as "nonsense".

 

I like having new folks join in here and if we treat them decent, they will come back and be regular contributors.

 

As far as I know, anyone who offers advce or comments here is not being paid for it. So if they choose to do so and they consider it to ba a waste of their time, they simply can stop at any time they want.

 

If I get close to a Traiblazer or an Envoy in the coming days, I will take a look at it and see what he is talking about.

No he didnt waste your time you did by posting something worthless. He ask a question because he wasnt sure what was going on now with that being said is the hole your talking about plugged on the inside? it may be. My wife had a 2003 Trailblazer and I know what your talking about but the hole was plugged down inside.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.
