Forced Induction SystemsDetailed discussions regarding cold-air intake systens, superchargers, turbo chargers, and other induction systems for your vehicle.
This is a discussion thread titled "Air Intake Confussion...", within the Forced Induction Systems forum, part of the Technical & Vehicle Assistance Forums category.
I've done and still doing my research and I am confused as to which I want to get because of the reviews. It's between the Airaid and Volant but here's the deal.
Airaid: Most say it's a little too loud for their liking, not as much or no hp / mpg added, bad design because of the simple shield (engine air is blocked my the rubber gasket when hood is closed), but at the same time - good quality of materials. And does it still whistle? Does anyone have it on an 08 Tundra 5.7?
Volant: It's quiet but loud enough when opened up @ high rpm, no noticable difference in mpg compared to stock (perhaps box design?), made of poor quality materials (just repeating previous reviews).
My main thing is how others review the intakes as little to no gains (according to their butt dyno) compared to their stock. I had an AEM intake system in my 4Runner and noticed the throttle response is better and so assumed that it had more hp.
A lot of these are reviewed from consumers who put the intake in their 07 Tundra. With a year difference for the 08, has Airaid figured out and fixed the whistling noise? Has Volant sealed the gap between the box and the fender?
My other main thing is I don't want to spend $250 or $370 for these intake systems if it'll do the same thing as a K&N drop in filter ($50).
PLEASE, PLEASE, PLEASE, Help me make up my mind. (I'm also affraid that the Airaid might be too loud... but if it's the same as the AEM, then it should be fine for me.)
So here is the low down....AirAid only loses the stock tubing if they see an increase in power...if they don't, they leave it to keep it quite...they have th ebest warranty on their systems, so if you dont like them, return it and you will get your $$ back. They have the same amount of cotton layer as everyone else, but they have a synthetic cotton layer to help prevent breakdown of the under layers, and they are using a higher grade rubberized compound so you don't have to worry about dry-rot...Volant is just over-priced. I run AirAid on all my vehicles and I love them. I refuse to run any other company's products...
Thanks for the input DunesRunner... I'm now thinking about doing the Airaid or K&N Drop-In. (I can put the $200 into my lift if I do the drop-in)
Some of the reviews I've read on Volant say that the Volant is more of a true CAI since it draws air from the inner fender walls, unlike the Airaid. I figure if I want the same CAI concept as Volant, I can do the K&N drop-in on my stock box. Anyone know the tone/sound difference between the Drop-in and the Volant?
For what it is worth...just installed a Volant on my 5.7 and have been pleased that it is not very loud but delivers when needed. Combined with my 70 series flowmaster, it has a low rumble, but is heard when I suck their doors off when I go by....Gotta love it!!!!

I recently put on the Airaid and have noticed the whistle. It isn't really that loud and it only happens with in a certain throttle range. I am very pleased with the results. The 5.7 is slightly snappier and at full throttle the roar is very intimidating. Also most after market intakes advertise a hp increase but what they don't say in the ads is it is peak hp at a certain rpm range. Most people don't drive around in that range anyway. I can't remember the range of the Airaid but it is up in the 4000 range. That is where most engines really start to open up. I like it and when I need it it prerforms nicely. The butt dyno says there is an increase but it is in the upper rpm's.

671 I hope you don't mind me piggie backing on your post. I was chosing between AIRAID and aFe. With the information from this post and some information from mine I have chosen to go with the AIRAID also. los211, at what throttle range does the whistle occur. I read on on another post that it was around 3K RPM. Is that accurate?

Not a problem at all beerguy. I received my Airaid intake yesterday and will put it on my truck Saturday (4/19/08) afternoon. I'm taking my trunk in to the dealer first thing in the morning to see what was up with all my dash lights flashing (4Lo, VSC off, Check Engine Light, and Traction Control Light) after I only had the truck for a week. Although they are now off, maybe the computer has a memory as to why the lights went off in the first place. I know I'm not the only one this has happened to. Everything is still stock so i'm sure it's not from something I did.
Anyway, after the install I'll post my reviews on the Airaid and compare the noise level to the AEM I had on my 2000 4Runner 3.7. So far, the people who have noticed the whistle seem to have the Airaid installed on a 2007. Maybe the 2008 model would be different.... I hope. Stay Tuned.....

I hope thing go well with your truck, I know what it's like to have problems with your truck after only having it for a week. I had mine for 5 days and had to get the transmission replaced.
If you don't mind me asking, Where did you get your AIRAID from? I'm in search for the best deal right now.

I ordered it from airaidheadquarters.com. It was $291.06 and when I put in the discount code: TS (Tundra Solutions) the price went down to $247.40. Shipping is free and was fast as it was coming from Arizona. Ordered on the 13th, sent on the 15th, and arrived on the 16th. I'd recommend them....

I have noticed the whistle around 1200 to 1800 rpm. I don't really here much other stuff after that as the exhaust starts to tone up. Usually it is with the passenger window down just cruising around town. The power starts to really increase in the 3k to 4k rpm range. I might add that with the window rolled up the whistle is very slight. My wife hasn't noticed it yet so I don't have to explain it to her just yet. She doesn't know I bought the intake yet! HEHEHE

I installed the Airaid yesterday, which took me about an hour and a half, because I wanted to make sure I was doing each step correctly especially since my truck is only a month old and has 400 miles on it.
Now for MY review: *please keep in mind, this is only my opinion/observation.
The Cold Start: is slightly louder than stock, but not loud as in the rumble or growl coming from the air filter. Just sounds like the engine is breathing better. On a scale of 1 to 10, 5 being stock, I would rate it at a 6.5.
Take Off: Throttle response is definitely better - It giddy's up right away. If you're like me who steps on the gas only to about 2500 rpm (easy take-off), you'll barely even know that the Airaid is there. On a 1-10 scale with stock being at 5, I would rate the 2500 rpm noise to be at 7.5.
From a full stop to about 2800 - 3000 rpm, that's when you'll hear this beast roar. That's when the its scale rating would jump from a 7.5 to about 8.5. Any higher rpm will bring the beast to it's full scale of 10 (Which I guess is twice as loud as stock)
Freeway Cruising: When cruising at a set speed - balancing the rpm between 1700 - 2000 rpm (65-70mph), I don't even notice anything - I'd rate it at a 5 with the stock maybe a 6. When I have to pass a car or accelerate (2500-3000rpm), that's when it'll slightly roar to an 8.
Gas Milage: Definitely a lot better!!! When I had my stock on, the highest I would get on my average mpg monitor, would be 13.5. Before I installed it, it read 12.3. When I took it on a test drive - stop and go for about 3 miles, the average mpg went up to a 14.5. It went up 2+ mpg just after the install.
The Girlfriend: She purchased the intake for me as an early birthday gift so she knew it was going on. When we went to run some errands, she was saying she couldn't hear anything (1000-2000 rpm). I kept telling her, I know - that's what I like about it - It isn't until I open it up that you'll hear something. When I opened it up to 3000 - 3500 rpm, she said, "Oh okay now I hear it, but it's not that bad." This is coming from someone who isn't into cars and drives a Chevy Cobalt.
The Whistle: Jeepers Creepers I have the whistle. It isn't loud but it is noticable. When I have the radio on, I don't notice a thing. But knowing that it's there is what still gets me. If I were to rate it on the same 1-10 scale, it would be at a 0.5 - 1.
It's only when the truck is in gear that I hear it. When it's in park and I rev up the engine, there's no whistle. That makes it hard for me to pin point where it's coming from. (unless I pop the hood, have my girlfriend drive it, and I run right next to it with a mechanic stethoscope.) I can't believe Airaid's engineers can't figure it out or at least come up with a solution. I teach art and ceramics and when I have my students make Clay Whistles, I know that there's a section on the whistle that needs to have a beveled edge. So I'm thinking that the whistle could be coming from the air filter mount, which kinda flares like a trumpet. But at the same time, in order for it to make a noise, the air needs to escape from some where. Hmmmm.... Maybe i'll play with the placement of the air filter. That'll possibly tune-it, maybe eliminate it. I'll be in touch.... Stay Tuned.
Overall, I love my Airaid.... the only down fall is the whistle, which could be drowned out by the radio. I don't do any towing so I wouldn't know what kind of noise the airaid would make if I were to. But I can see how it's aggressive tone can get annoying during long distance towing considering the rpm would maybe be at a constant 2500-3500 when towing.
Oh yeah, and compared to the AEM that I had on my 2000 4Runner v6, it has the same aggresive tone but 50% louder 20% deeper. I guess since I now have a 5.7 V8.
Hope my review helps... BTW, sound clips don't do these things justice. It's good because it give you an idea of the tone. The volume on the other hand is a different story. The microphone only magnifies the sound so it'll sound louder than it actually is on sound clips.
Great review 671. I'm hoping to order mine this week, better halves approval pending. Are you running a stock exhaust?
Yes, I still have my stock exhaust. That will be changing soon though... it should be shipped out tomorrow so hopefully i'll be done with my performance upgrades by next weekend. (Intake and Exhaust... I don't think i'll be doing headers.)
