Chevy Trailblazer Volant Cold Air Intake & Throttle Body Spacer Installation 

Thank you! I really lucked out and got all of the aftermarket parts from my local auto salvage yard. I just got all new suspension with a lift kit that I will be installing very soon and posting new videos. Please subscribe to the channel if you haven’t already 🙂

No problem. I hope it helped you out, Marco! Please hit that “SUBSCRIBE” button and stay tuned for future content!

That’s awesome. I recommend using that spectre filter with the OEM air filter housing. You’ll probably have to gut the plastic from within the factory housing to make space for your new filter. But it will be much more functional rather than if you were to leave your new spectre filter exposed on the hot side of the engine bay. Hope this helps! Good luck with your install 🙂

@@PASSIONBUILT I was just going too leave the cover off lol, & thanks man :)

@@lovellmills7959 I thought Volant stop making them until I just came off their website! Mines is a 2005 & they don't make one for my year but the 2006 looks just the same. I don't know if there's a hose to be blocked off under the intake tube but I think I can work with it👍🏿 I just took the stock muffler off a put a Dynomax from Summit Racing & it definitely made a difference in performance a bit & I picked up better gas mileage & I run 93 oct ! I'm looking to do the Cold air intake & Summit has a plug 'n play performance chip that will give an extra 35hp. Got some fresh Mobile Oil & Wix filters going in Monday & New AC Delco Iridium spark plugs are on the way. You can't be fart'n around on I-285 in Atlanta, you gotta merge doing 70 out the gate🤣

@@MrBigR928 Yeah it's weird. No company makes a cold air intake for the 03 too 05. But 06-09 they did? Mine is a 2005 So I bought a Spectre filter installed it and left the air box cover off. Doing that it exposes the "intake resonator" (my God who tf ever at GM Designed that???) 🤦🏼‍♂️🤦🏼‍♂️🤦🏼‍♂️ So I had too find a way too block it off. I thought about putting an exhaust on it but it dont make sense doing that kind of work on an inline 6. Plus mine is so clean my Trailblazer LTZ with 267K literally looks brand new from the factory underneath inside and out I Couldn't cut the exhaust up! I also have a 2003 Avalanche and for that one I did a Flowmaster Exhaust 😍 it's on my channel shorts if you'd like too check it out.

That’s awesome. Thanks for the input! It may help someone else that’s looking to make one themselves. 👍🏼

@@PASSIONBUILT thanks I appreciate your reply. I have a picture of the mod but Facebook doesn't have the ability to post pictures in thread. If you take a stock airbox from the junk yard and hollow it and cut a scoop in the front it will be just like a Volant box. You would have to insulate it. I always tell people if you going to mod your stock stuff get extras from the junkyard.

I completely agree with that. You can always grab extras from the junkyard for cheap in the event of a cut gone wrong. I actually mention in the video about other trailblazer owners gutting their factory housing in attempt to replicate the Volant housing.

On the 4.2 models, the engine looks so weird without the factory resonator box installed. I don’t mind it too much.

At 00:47 of the video I mention that I plugged the air injection hose due to having a 2003 model. 2002-2003 did not have the air injection system. I removed this intake from a 2004 Trailblazer at my local auto salvage yard.

@@PASSIONBUILT ...I didn't mean the inlet on the intake. On the airbox...maybe my terminology is wrong...where "vortech" is written..there is a small hode that runs into the top of the block. That's the one I was speaking of

@@rjlegacy38 There are 2 vacuum hoses that run from that resonator box that you're talking about. They both fit as they should with no issues even with the relocation. It's only about a half inch difference. Nothing too major. I can say the larger hose that runs from the breather on the valve cover to the resonator was a tighter fit than before the installation. But still installed using the factory hose.

Hey there. Honestly, the fuel economy didn’t change really. The most noticeable gain was the intake sound. But didn’t get much out of it performance wise. Probably with a tune from PCM of NC I would notice a change but as of now. Not too much of a difference in the drive. But for how much I paid for this set, which was like $10 or less. Definitely a cool upgrade! Lol

@@PASSIONBUILT thank you so much for the responses. Do you have Instagram? If so would like to share with you some of the mods I did on my 2006 trailblazer. Great channel keep up the good work

Thank you! I appreciate that! Please subscribe to the channel if you haven’t already. I have more trailblazer content coming soon 🙂 As for Instagram. I have 2 accounts but rarely use my personal. @jonathanrohena or @PASSIONBUILT

Fitment should be the same. Just 04+models came with that secondary air system that I blocked off as you saw in the video.

@@PASSIONBUILT Appreciate you.

Did you delete your factory resonator that connects to the breather on the valve cover in install you CAI? If so. That’s your problem. If you’re using a cheap eBay intake kit that doesn’t utilize the factory resonator. There are a couple of problems. First being the issue you’re running into and the second being the metal intake pipes get heat soaked by the exhaust manifold. The kit I installed on my trailblazer from Volant retains the resonator and is made of plastic so it doesn’t get heat soaked.

Hey Alan. Since I installed all of these parts at the same time it is difficult to tell if the throttle body spacer actually made any difference on it’s own. I honestly don’t think it did. Online you can read about a whining noise that throttle body spacers create and I can tell you that it does make a whine noise that is noticeable upon acceleration but you get used to it after a while. Overall, I wouldn’t pay the $75+ for one. But it sure was a cool part to find brand new in the box for free.

@@PASSIONBUILT Yeah, I'll bet it was. I have read so many conflicting opinions about whether a CAI really helps or not, that I can't help but be confused. If someone installs the type that does not seal out air from under the hood, I would think that it would actually make things worse with all that hot air coming off the engine and through the radiator. I'm not going to waste the money on a TB spacer, but I have been toying with the idea of a custom made enclosure for a CAI. I've also read a lot of comments that people are getting DTC's after putting in a CAI.

CAIs on these are made differently. The kits that you see that have no air filter housing and have metal intake piping are not beneficial at all. The one that I installed from Volant is full plastic and has a complete enclosure for the air filter that has a larger opening for more airflow from where the factory air box would suck air from.

The only place where throttle body spacers do anything for performance is lower rpm’s. It’s not a seat if the pants feel that you can tell, but if your pulling a trailer or have it loaded down with your whole family in the back you would notice that it would take less effort/less throttle input to plug around in stop and go traffic. That is it, it does absolutely nothing else for the entire rest of the RPM range.

The intake is definitely noticeable under heavy acceleration.

im guessing since the kit comes with a tiny breather filter it's for that...

It’s called the air injection system which comes on the 2004+ models. I capped it off, as shown in the video because I have an early model trailblazer. I’m not sure what will happen if you cap yours off.

did you cap yours off? if so,did it set off your check engine light? just wondering. getting ready to install mine. @@PASSIONBUILT

An OEM resonator. I’m sure you can find one on eBay.

What a great deal! Gotta love good junkyard finds 😎

Intake and exhaust are always a great starting point. Depending on what state you live in. You could always delete cats as well. If you’ve already done the basic bolt-ons. You could have the heads ported and polished. That always makes for a nice upgrade but can be costly and isn’t as easy.

WHY ARE YOU YELLING?

@@PASSIONBUILT IM ACTUALLY NOT I CAN'T SEE NORMAL LIKE MOST PEOPLE BUT NON THE LESS IM CURIOUS AS TO WHERE THOSE VACUUM LINES GO ONCE YOU'VE CHANGED THE INTAKE???

K&N is definitely a high quality brand and I love their products. But I got this set from a Trailblazer in the junkyard so I did not get to choose which brand. However, I will say. I do like this kit's design a bit better because it has the closed box housing for the filter. From the pictures I have seen online, K&N's cold air intake has a heat shield that surrounds the filter but doesn't completely seal it off from the heat coming off the header. But other than that both kits are very nice.

@@PASSIONBUILT you can buy the k&n tube and couplet for 40$ and use the volant cover but you would have to call k&n to make the order
