I would return it back to stock and see if the feeling goes away.

If you floor the car @ 1500-rpm's it's going to "Bog" however what you are feeling has to do with the drive by wire set up, not the intake system.

If the system caused a drivability issue, I think we would have seen something come up with all the testing we did and I am sure the beta testers would have brought that up as well.

If you can, go back to stock and see if it still persists and let us know.

Thanks,
David

I don't ever "floor" my car at 1500 rpm's, I don't even drive at 1500 unless im in first gear just waiting to get into second. Honestly, I haven't noticed any bogging under actual load, it's just getting going from a start. I can assure you I have never felt this before but it does kind of remind me of the first day I got my BRZ and had trouble getting used to the clutch engagement point. If I read correctly, at least one other member is having this issue. I noticed this literally the first time I got going after I finished the install and thought "hmm that's strange". Didn't really mind it until I realized it kept happening.

I could take a video of this but if I don't use multiple cameras it will just look staged as if I just didn't let out the clutch enough. I'm gonna go back to stock on Saturday and report back how it is.

EVERYONE, CHECK THAT THE 90 DEG BARB WILL FIT IN YOUR INTAKE TUBE BEFORE YOU START ANYTHING!!

GAH! Should've checked before I tore everything down. I'll have to run to the hardware store to see if I can get the right part. Good thing I have a spare vehicle, no way I want to undo everything and put the old airbox in.

I realize this item comes at a great price point, but would it have been that much more to have some of these parts already installed during the assembly process? I know some parts need to be put on due to the installation process, but some of these parts on here could have been attached by AIRAID, IMHO.

OK, I sent David@AIRAID a PM, but in the meantime, I assessed the Barb Elbow and the Intake Tube and determined that the Barb Elbow is actually the right size as described in the packing list and instructions. The Intake Tube has a 1/8th threaded opening while the Barb Elbow has a 1/4th threaded nipple.

Those of you with the correct fitting parts, which is correct, is the elbow supposed to be 1/8th or 1/4th? For now, I reduced it with a 1/4 -> 1/8th adapter and a 1/8th male/male nipple as shown below.

EDIT: Just spoke to Ben @ AIRAID and it appears the tube itself has the incorrect threading. They're shipping out a new tube to me ASAP. Not sure if my reduction hack is going to cause some performance issues or other problems, so I'm just going to keep the car off the road until I get the new tube in place. Thanks to the folks at AIRAID for the quick response!

Also - at first I couldn't figure out how the firewall plug was supposed to be installed. It turns out you have to remove the stock grommet completely, then push the firewall plug in from the engine side and give the center part a good push until you feel it click.

At first I wasn't pushing it hard enough and it kept falling out, so then I tried it with the stock grommet and that didn't really work either. Then I tried different permutations from engine side as well as cabin side.

I am also having the 'bogging' issue. First off, I wouldn't call this a bog. It feels much more like a complete dead spot in acceleration. Some people seem to be reading the term 'bogging' and just thinking of a car that isn't accelerating. This actually feels like the engine suddenly cuts fuel or lets in to much air and so tries to stall. This is not just a flat spot in torque or power.

I've noticed it when both moving from a dead stop (takes a measurable, noticeable amount more pedal travel to avoid stalling and to accelerate) and when doing the 1-2 shift I need to be further into the pedal travel for a smooth shift. It's also noticeable if you drive in 1st gear at a parking lot speed using the lightest throttle opening you can without bogging or stalling the car. I have to do this on a daily basis due to my awkward parking spot at work and I can say with 99% certainty I'm having to step much further into the throttle putter the car along at 5km/h. At throttle load above 40% you don't notice it at all even modulating the throttle. It only seems to be at low speeds with high engine load.

For record, I am on a completely stock car other than this intake and I am running 94 octane no ethanol fuel like I have since day 1. I drive the same boring route to work daily and know my car like the back of my hand. I need to put more throttle into it to move up my inclined driveway at parking speeds, or up the long steep hill I drive up to work every morning that hits that lovely spot that isn't quite slow enough for 1st but isn't quite fast enough for 2nd.


The best way to sum it up is It feels as if there is a much larger off idle dead spot. Similar to a dead spot in a TPS or a mild vacuum leak.

It also seems to come and go, and it has been quite cold here the last few mornings so I'm wondering if it might be enivornmental

I've gotten a second opinion on this and this is definitely not in my head. I'm actually going to put the car back to stock tonight so I can do repeated tests to isolate this further and am prepared to start logging to prove that this is occuring.

I can honestly say that if this isn't something like installer error or a simple fix, I will be putting the car back to stock as it is noticeable worse to drive around town and at low speeds. I really hope its just as simple as I have a coupler installed funny and it's got a slight vacuum leak.

I've taken mine off and re-installed it twice and still have the issue. Perhaps I am doing something wrong on the install, but it seems pretty easy and straight forward. I've rebuilt motors and done plenty of engine swaps so I hope I could handle installing an intake haha

Also, what mods do you have?

I've also reinstalled my intake and am not green to cars either, dealing mostly with boosted applications I have had my share of learning experiences from improperly aligned piping or couplers leaking under boost or vacuum.

I was very careful to install the couplers correctly and even sealed around the PCV connector to make sure it's air tight.

Zero mods other than this one.

Thanks for the understanding.

No problem David - but we're not talking about a aftermarket tune. We're talking about YOUR intake and problems that some people are having.

I am concerned about the problem because one of the guys having a problem is a customer of mine who didn't experience any problems until the intake install.

I will be getting data and reporting back as it pertains to your product not mine.

Wow, a lot of posts apparently got deleted.

I'm sorry but this is a feedback thread and I, as well as other STOCK people have posted our feedback with issues pertaining to intake. Maybe you weren't expecting people to have issues. It's clear you've spent a LOT of time designing and bringing an excellent quality product to market. I commend you for that. However, deleting posts is rather childish and shows lack of character.

There is clearly something going with how this intake is reacting on certain people's cars. Multiple people have posted as such. All we are trying to do, Visconti included, is figure out what it is so that we can ultimately have a better product. Isn't that the point of having a community forum? Would you rather I start a separate thread titled "Bogging issue with AIRAID intake diagnosis/discussion"? Probably not.

EDIT: I'm not trying to be a dink or anything. I just want this solved so I can enjoy the intake all the time, not just when I'm on the hwy.

Hello 2forme,

Post's were cleaned up that had nothing to do with the AIRAID.

If you had a Tune and the car ran fine and then installed the AIRAID and you are having a problem, then the TUNE needs to be adjusted to work in conjunction with an aftermarket intake, which clearly it was not designed to do, nor could it be since these were just released.

This Tune was clearly designed to work on the Stock Fr-S/BRZ car and now aftermarket part's are being introduced, so the Tune will need to be adjusted to work with the aftermarket part's. You can't expect a Tune designed for a stock vehicle to work in-conjunction with aftermarket part's.

Not sure how familiar you guys are in the Mustang or Camaro world, but those car's are so sensitive that each respective aftermarket Intake does require a different tune. It appears that is what we have going on here, which is fine, but that needs to be discussed in the Tune thread, not Intake thread, if that makes sense.

If you are 100% stock and are having a issue, then that is something we will absolutely look into, but if you were running a Tune and then installed the AIRAID and are experiencing any issues, then that needs to be adjusted in the Tune to accommodate for the respective intake system.

Thanks,
David

David your making this a very painful process. You have multiply people here trying to help and you just refuse to let us.

Like I've states like 5 times now , I'm going to collect fresh data from a stock car with and without your intake, wish and without my tune in efforts to sort this out. But everything I've seen do far is your intake causing the maf sensor to do crazy stuff at low rpm , high load. Stock tune and tuned.

Deleting our posts won't make this go away. Deleting my posts just pisses me off

John

[2forme]

As far as I've seen, I'm the only one with a tune who has posted any issues. The rest were stock tune...

[raz0rbladez909]

To me deleting posts just makes it seem like there is something to hide. I've had interest in this intake and would like to know full and well what it is doing before I place an order. If I can expect a vendor to delete honest intentions to help from other sources then their product will not be the one I will purchase. I doubt Visconti has any intention to do anything but figure out what the problem is.

I am 100% stock and having this issue.
