AFE Momentum GT on 6.2L noise increase?

ChristopherDB · June 25, 2018

I've been searching but can't find any videos showing the noise difference between stock and this intake. I'm interested in purchasing it but worried about how loud it will be. I know there's a plug that can go in the front to quiet it down a bit but saw several forum posts of people that removed it because of the noise. I don't want to spend $400 and then end up taking it off. A video comparison would definitely help my decision.

I added the GM performance exhaust last week and it gave it a good sound without getting too loud. Thankfully my wife didn't even notice. I don't want this intake to push it over the top.

I used to have one. Barely a differance

Bought one of those sealed cold air setups, popped the hood, my tech says it looks like what your factory system already has and you’d wind up attaching to your existing air induction. Seriously, I handed it back and just switched out the filter with a K&N to allow more unrestricted air flow, $500 system to a $50 filter.

I have the Volant sealed cold air intake kit for my Sierra. It was night and day difference for how loud it was. I added the GMC Borla exhaust this weekend and it made it alot less noticeable. It makes it bearable now. If not for the exhaust I would have probably sent it back.

Most aftermarket air boxes are noisy because you have a straight tube to the intake, no baffles. You can keep stock cold air box buy the tube same noise. Put the filter of your choice. Till I was 60 I wanted all the sounds intake, exhaust. Now one noisy the rest quiet.

I added the junior Airaid system with the smooth tube and dry filter, it's a little louder when you get down on it, but otherwise not noticeable.

I have just the stage 2 AFE intake on my L86 and it screams. Any time you are under load it will turn people around to see what is coming. I don't even feel the need for exhaust anymore, any time I want to hear the engine you can now and it sounds great. Nice and quiet until you want to be loud. No drone from an aftermarket muffler fighting or helicopter V4 mode like you get with a cat back. This is the first CAI I have put in a vehicle and I will be going this route rather than cat-back exhaust systems from here on out.

some lame info in this thread. I have had a K&N (tried it left over from a previous truck - fit exactly the same as an 04 Silverado) a MIT jr with a bruteforce dryflow, and now the AFe. Ah, not at all the same between any of them. ran a cut up factory box with the air raid jr. an both the K&N and the bruteforce AEM filter.

* K&N is not a good filter to run, sucks too much dirt with the increased breathing, even mild sparingly oiled can foul a MAP sensor. I would not run in this application. saying its the same a an AFE GT momentum is a joke and not to offend but shows how much knowledge you have on this subject.

* Airraid junior with filter and modded OEM airbox - gets rid of the silencers, seems to have slightly better response (with modded box - not stock) clean appearance, more sound. dyno'd on stock uncut box provided no increase in power. Mine had material removed and a highflow dry filter. (not for wet applications, rain no problem, deep water - at your own risk).

* AEM dryflow filter - excellent. better than oem flow, close to oem protection.

*AFE GT Momentum - if you didn't notice anything you probably did not reset your computer (I found it needed to be reset). To me intake sound improved(sounds like a strong small block now which it is). low end torque was notably stronger, def improvement in breathing of the engine. truck sure does feel stronger and is seeing more air than the other set ups I tried. That said I had an initial increase in mileage, now it seems to be costing 1 or 2 mpg. but for me it is worth it. Does feel quite a bit quicker as well especially going back to stock which I did to take into the dealer. truck felt like a chocked up slug comparably with the stock intake.

I agree with 10sierraA.T. the sound under a load is fantastic (subjective I know)

did a home port throttle body along with the GT momentum and driveability, overall power, and response improved quite a bit as these trucks are very restricted stock.

If it sucked I would have gladly switched back to any of the other cheaper options and returned the Afe. I'm positive with tuning I would gain back the mileage and see even more of an increase in power.

with any of these options if your not running 91 or better you will not see any gains as the motor will in most cases pull timing . so stick an great intake on a 6.2 L86 and continue to run low grade fuel don't expect to see anything.

WOW, me, my father, my brothers and probably several hundred customers over the years must have been lucky. All those oiled Amsoil air filters and K&N cold air intakes we used over the years. No sensor problems or increased oil use from those lousy filters. All those dusty pipelines and utility lines we travel up and down. Whew, thanks for the heads up.

it's a known problem genius. Find out if GM ever voided a warranty for a K&N or burnt up a transmission cause oil on the MAF.. Just cause you are unaware doesn't mean the problem does not exist. good luck sounds like you got it figured.

Next time I mod something I'll make sure to check knowledge with you. I'm just off the street.

I’m not just off the street, let me know when that class action law suit comes about with K&N or any other oil bath air filter.

Well I am just off the street and fell off a turnip truck at the same time. You seriously have to been living under a rock not to know this information.

K&N's flow the most dirt. been tested a thousand ways to Sunday (good\gle it) same thing on any chevy truck with an LS or newer gen LT with an electronically controlled trans and a MAF has been documented failures due to oil on the MAF sensor. Again just cause you have not heard of it and use K&N and amsoil does not change any facts.

OK here's a test go spray your MAF with K&N filter oil and let us know what happens? If you do own a 92' Silverado (in Your sig) you have a 700R-4 that does not have an electronic valve body(you could still experience TC lockup issues with an oiled MaF). This issue really applies to 4L60-E and up with an LS or better & a MAF. (again google is your friend). I hope at this point your just joking cause this is like a 101 level tech issue that's been fully documented years ago your vigorously debating against cause you don't know about it.

no more back and forth you won!

The problem most people have if they have one is caused by the re-oil after cleaning, the nut doing the re-oil. The 92 has a K&N, the one in it is 10 years old. Being it has a blower its pulling more air. I’ve use or sold many oiled drop ins or cold air. Anything that’s produced usually someone somewhere is going to have problems with it.

My old 2002 Furd still has a K&N setup from the first air filter change and my son now has it +200k miles. It doesent smoke or lose oil and runs like a top. The problem isn't how much dirt gets by but how much the dope that cleans it over oils it and doesn't let the oil tack up before reinstalling.

I have the exact setup OP is asking about and it does increase sound level. To anyone that hears it it is not loud or obnoxious and to car guys it is the music of angels.

kennerz · July 6, 2018

real point is somebody mentioned that the GT Momentum does not work. totally not true. I'm not a cold air fanboy, however it's a great design that works as far as both sound and performance and is priced competitively. I like mine and would not want to go back to stock, truck sounds and pulls much better for just an intake.
