IIDXholic, i tried that intake on my TL, you didn't know?

The only thing I love about Infiniti

BukvaMan

For a long time i had it in its full configuration. Cai so to speak. The low end sucked and there was a delay in throttle. I switched to Sri and things were much better but since the filter was under the hood and being heatsoaked i figured why bother at all. For the sound it wasnt worth it. I rather have a healthier engine and switched back to stock. I was pleasently surprised.... And keeping it that way. Im sure if i put the stock cats back i wouldnt regret it. Im a little lazy to do so....

MEKO

Yup... just like what I felt.
But yeah in a hot summer day, K&N SRI was the worst thing happend to my TL.
Even around 75F it made the throotle powerless.. after that, I started to do fin out something before the summer... now it's much better

well its mods and supporting mods....some mods move the power curve up....so for instance if you had the ATLP jpipe and exhaust and CAI....you will have a monstrous top end but a shitty low end...

i did a take a video when i was coming home and i was right around the 5.5 second mark between the same rpms....

BukvaMan

I agree but its very rare lately that i push my car... in my case it would be much more fun if my low end was stronger then anything else. Especially on a car that has very little low end to begin with...

I really might start reverting back to stock... the only thing i will keep is the exhaust and possibly the j-pipe

MEKO

iTrader: (1)

Like swoosh said,
ATLP J-Pipe and Exhaust and CAI it total high end
and to me
RV6 J-Pipe and SRI is low end

I would always aim at low end on this car, Vtec is already high end
The car is heavy + has low torque, of course you have to focus on low end

all we need is god damn ice box for the SRI


Swoosh, any chance we could see the video?

iTrader: (5)

bro i remember you telling that your car feels sluggish and stuff....it would be your ECU is pulling some major timing....i have kept an eye on my timing and am always in the +35deg range....when i idle am sitting at 8-10deg....sometime i drop to -8 or -10 but that is when am coasting to a stop....

i would suggest hooking up a OBDII reader and checking your timing and AFR....is amazing how quickly the timing changes and how it messes up the power delivery....

sure....let me upload it....its not the best of vids LOL....i chopped off half of the speedometer LOL....

or let me take some decent vids tonight and post em up

^Meko keep me posted when you do go to that custom Fab place.......and damn how can you love 4th gear.....I can't stand 4th gear , it is so freaking slowwww!!! Wish I had a 6mt FTW!!! !

MEKO

iTrader: (1)

i still couldn't go to them
the place is in Woburn, and im leaving woburn at 7 every morning, and school finishes at 3
and they close at 3
friday is the only time but im keep having things to do, this friday i will have to go to school at 8

next week semester finishes, soo i'll let you know next week

yeah it's not like 3rd gear but i love the sound it makes because of where the rpm is
it's not that slow also, easy to pass a car on a one lane road
well, with 77-80 mph

swoosh

iTrader: (5)

^^^ Sorry Meko....I will def record a video tonight....

Boston, I concur, the 4th gear was the main reason i did the diet....i hate that gear with a passion

^^^ swoosh, I had a request for a video of my CAI setup. Maybe we can do that this weekend.

MEKO

iTrader: (1)

^ mean SRI right?

Swooosh i don't know bro, isn't 4th gear enough to take over a car? It still pulls unlike 5th.
I don't drop it to 3rd when I am passing someone on highways with 80mph.
3rd becomes too much

what the hell we need 3 and a half

my 3rd gear started to kick (sometimes) i dunno why
just replaced the 3rd and 4th switches too

still didn't order the redline though

jungy4

That was me. CAI or SRI?

NSXRguy

I think the b/k series crowd are experimenting with 3.5" and even 4" intakes with power gains. Is the aem cai 3" diameter??? Im curiouw to know what kind of gains or losses those sizE intakes can do for the J35

MEKO

iTrader: (1)

AEM is 2.75" as I know.
Wish it was 3.5"
swoosh has like 4.095898593" SRI, I want to try a big diameter one too but don't want to deal with custom pipes again

BukvaMan

how much can an intake be better i dont know why you guys are going crazy over it... I had mine for more then 3 years and have stock now. Im pretty sure that im not missing anything besides the sound maybe.

On the cai low end sucks and the throttle response too.. SRI was better but didnt make sense over stock. Then on top of all that you have a filter that doesnt perform up to stock so why bother.

d_prada1

my setup.

I used the factory mod. I upgraded to a k/n drop in and cut all the resonance baffles in the airbox and cut the stock grill JUST where it aims the air for the intake. I didnt cut all of the grill since half of it routes air to the radiator.

IMO its not loud at all. Slighty howl up top. Performs really nice at night and above 30mph

iTrader: (5)

^^^ haha nice

NSXRguy

Prada, do you a have link for the "stock" mod you did for the intake? What pipe did you use for that end pipe with the opening?

MEKO

iTrader: (1)

^ The pipe under the battery cover (front of the battery, below the trianglular cover)
pull it off, comes out easy

BukvaMan, intake is the only thing you should go crazy about a car, rest comes after.
Lots of people don't know the importance of it..

That sounds really good. Thanks for posting. I am going to order this intake!

Thanks Steven...
Classic deep sound of AEM.. I like

What's the diameter of the stock intake? I want to remove the silencer and just straight pipe that section.

Anybody have a current link to the AEM SRI? I can't find it on eBay and it shows unavailible on Amazon, I'd rather go that route than CAI for a DD.

Steven Bell

350, I looked up my exact order, but it said it is currently unavailable-sorry.

any updates on mpg with the SRI?

bouncer07

Spring and Fall you will get great mpg's no doubt, but when Summer comes with high temps, your car will pull timing from the heat soak and will lose mpg's from high AIT's.

Thanks for checking, I found a CAI on ebay for $75 shipped that is in 2 pieces, so I could make it either SRI or CAI, worth a shot, if the filter is too junky I'll go buy a K&N or AEM. That way I can try SRI and CAI.

Steven Bell

iTrader: (2)

So far, I have not noticed any change in MPG.




Sounds like a good option then.

MEKO

iTrader: (1)

What MPG does stock intake get? 04-06????
I forgot mine, I can't compare anything.
I could explain the performance difference as did at first post but not MPG.

Any update on removing resonator????
MPG? Performance?

Looks like they have a few color options, like black/red/blue/silver tubing, they also have the DC CAI, wondering if it's the same thing without a sticker.

MEKO

iTrader: (1)

I see..

It looks like K&N pipes...just the bottom of CAI extension is bent a little.
SRI pipe is too short and close to engine
That's why I extended my K&N SRI. Just like AEM SRI Steven Bell has.

Filter that has the middle part opened, is Spectra.
Didn't try it but AEM is better than rest.

I would wait and look for AEM SRI. Did you call them?

jungy4

Steven Bell's intake, is the entire intake made by AEM or just the filter?

MEKO

iTrader: (1)

As I know entire is AEM.
Because I never saw that pipe before, and was what I was looking for since a year.
It's like extended version of K&N SRI but the pipe is powder coated nicely. It won't soak heat.

K&N or the ones on that ebay link has cheap pipes. It gets hot as hell.
check Steven's engine bay picture again, you'll see the quality on the pipe.

MEKO

iTrader: (1)

I just called AEM

They have no idea about the Amazon kit (links are on first post)

SRI on that ebay link might be longer like AEM SRI or let me say Steven's intake.
I can't say anything from a picture.
Try it..

I hate cars

OMG!!!!!!!!!!!!! I did not know this kind of thinking was still going on.

1) A filter can never and will never affect mpg.

2) Cold air makes more power than hot air.

3) The stock air tract including stock filter is not a restriction, "improving" it can't make a difference in power. There's no measurable vacuum in the stock intake tract at full throttle.

4) Anything you do pre-throttle body to the inlet tract will not affect the powerband. It is absolutely impossible. The filter and inlet tract is invisible to the engine. Exhaust mods can slightly alter where power is made in the rev range. Intake mods are not the same, even if you went from a restrictive intake tract to a free flowing one, the powerband would remain the same. Intake mods absolutely can not reduce low end torque. You could run an open throttlebody and no reduction in torque.

It doesn't matter how long or how short the tube is before the TB, only the air temp matters. Look at what happens after it passes through the TB. It goes into the plenum, a big open chamber designed to provide plenty of volume for even air distribution into the runners. The plenum has a slight effect on powerband and the runners have the largest effect of any other intake tract part. Think about why Acura uses variable length runners and you can actually hear and feel when it switches over to the short runners at high rpm. Making a variable length/diameter intake pipe between the filter and TB would have been cheaper and easier.

You have a big freaking butterfly valve right in the middle of the intake tract whose sole purpose in life is to restrict airflow or "throttle" the engine. That's why it's called a throttlebody. If a less restrictive air inlet tract helped mpg, you would get your best mpg when the valve is fully open, aka full throttle. You would get your worst mpg with it closed (high restriction) aka idle.

Miles per tank is not an accurate way to measure mpg and all you have is wildly varying conditions.

There's no data, only subjective thoughts like the engine "feels more relaxed". Acceleration videos tell nothing. Only a dyno with the hood closed would be somewhat valid. There's no data here.

Most people hear the additional noise and think they "feel" more power. It takes 30-35hp to feel a change in a 3,500lb car. You are not feeling a change with a SRI or CAI.

To recap, you're taking the non restrictive factory semi-cold air induction, and throwing a filter under the hood so it can suck in a bunch of hot air and claim it makes more power and mpg but with no dyno.

I'm not trying to rain on anyone's parade but enough is enough. If you like the sound, more power to you. This thread is a great read: https://acurazine.com/forums/3g-tl-performance-parts-modifications-112/experiments-air-intake-temperatures-868353/
