Before this thread gets locked, I'd like to state something. I think the extremes of both sides of the argument are unfounded. On the one hand, you have a guy stating that 80% of CAI owners will return to stock. I don't know where he got those numbers from, but I suspect they're a tad...off. The guy's original post sounds a little too "propagandish" to me.

There's no doubt that there are numerous dyno sheets proving the gains of the installation of just a CAI. However, these dyno sheets are also a marketing tool. The results will be the best run on the best of days, under the best of conditions. I don't know how much they would pertain to the harshness of daily driving. Would the loss be more on the hottest, most humid day? Or would they be minimal because of the added air stuffed into the block? We really don't know until someone runs stock and modded on a dyno EVERY DAY.

Bottom line? I don't think the loss is as bad as some people state, and I don't think the gains are as great as the sheets will lead you to think. Swing away.

Potato pancakes are good.

Again, if the car could be tested having Air RAM into the stock intakes! it would give you the HP your looking for! reason aftermarket intakes give that HP boast on a dyno is because you are running the car at max speeds with open filters! it's not real world driving

you do realize when on a dyno they have large fans blowing air into the front of the car for intake/cooling purposes. it may not be 100% accurate for actual speeds you hit at the high end on a dyno but still there's air.

even "real world" driving i'll take my aftermarket intakes over those giant ugly inefficient air boxes any day.

I will be at Z-days, I would love for someone to ride in my car with stock intake and only thing I have is a F.I CBE. I bet my car will feel more alive. Then someone with tons of bolton's

My case I have spent about $3000K on intakes for all my cars and all of them lost power and GAS.. Oh and I had the NISMO intakes on my 350Z NISMO 08 HR and it lost power.

i ran my car with just FI CBE and stock intakes for over 10k miles. put my intakes on and it's way better.

you havent made any sense what so ever in this thread. :facepalm:

and i'll be at zdayz as well. i bet mine runs better lol

lets make sure our butt dyno's are calibrated before making any serious statements. :mad:

This has got to be one of the most pointless threads ever. The OP's arguement is basically, what's the point of spending all that much when all you see are small gains until you reach the peak powerband. The thing is, we're looking at the Z as a performance car where every hp matters. There is absolutely nothing wrong with going OEM and keeping everything stock. At the same time though, there's nothing wrong with some engine bay bling or a few extra pony's. You don't have to hit the redline every time you drive, but it's nice to know it's there. If all I did was drive the Z like an old lady, I would have been better off with buying an FR-S.

Modifying your car with aftermarket intakes and exhaust has nothing to do with logic or common sense. It's fun. YOLO

Yeah but it's good for several pages of forum entertainment which is why we're all here reading this anyway.

The smart thing to do would be to buy the parts piece by piece, but don't install till you have all parts. Make sense?

fixed

That's mainly what I was getting at but at the same time you are always going to be tempted to play with that brand new toy lol

My background is I.T Engineering! and I look and feel and research everything to death!

I can't get out of my head as to why NISSAN pulled HP number from NISMO and IPL to 350HP 348HP with just high flow CBE and tune.

The intakes did not change!

NISSAN has pulled everything they can out of the 3.7L setup! so why on earth do we think an aftermarket business like Stillen or Injen knows best and is able to make more HP then OEM???

If that is the case why does NISSAN pay there engineers $100 per hour to get as much HP as they car? why not just build a setup like Injen or Stillen?


I understand you want that added HP at 6500K but at WOT with OEM, I don't feel anything more or less with the Injen setup just that the Injen and Stillen are louder!!

I took apart my whole intake setup and after looking at it, it's very good design.

So why is the aftermarket setups making more HP or seem to be?

I will be getting my car dyno at Z-days to see my WHP with stock intakes and F.I CBE with tune.

This thread is still growing? Kill it. Kill it with fire

this is because aftermarket companies are TRYING to get max performance. Nissan just bumps it a but to make you pay extra money for a nismo or IPL.

aftermarket makes more power because that's the point. free up HP that OEM denies.

look at the GTR. intake, exhaust, and a tune and the thing can jump up 100AWHP just by taking away air restrictions.

you say you research this all to death but i feel like you havent. possibly just stuck on the idea OEM is better? i dont know why but you need to realize it's not :shakes head:

i'm not sure now if you're trolling or just stupid at this point.

No doubt, but if you're serious about performance gains??? The way I said it is the only way to really get it done right.:tup:

The thing is, I have seen several independent dyno graphs where long tube intakes made power across the entire power band (most of which is higher up like you mentioned, but still making 4-8 whp in the low end) When people do cbe plus lth/tp/hfc, yes the argument can be made that intakes are not needed because they will provide only small gains at that point. By themselves though, I would think adding 20 whp up top, and about 4-8 everywhere else is not too bad.

Also, Your argument is people are wasting money on something that doesn't help the car or hurts it's performance.... To be honest, isn't that what you did by buying an IPL? it's performance advantages are slim over the standard G37 but yet it costs $10,000 more.

He doesn't own an IPL.

what's the difference between an IPL and a G37 IPL performance package?

Good thing I track my car and don't lose sleep over $500-600.

I just trying to really understand why people feel they are getting more HP from aftermarket part?

How would you feel if I told you that Stillen did not do any R&D and they just took some pips and filters and design them in such a way to lean out your eng to run richer so on a dyno you see more HP? you feel pissed off right? or would you still buy it because you think in your head that if you are putting an aftermarket part on your car that it's got to be better design and NISSAN is just holding out on HP.


If you go and talk to MINES of Japan or Amuse Powerhouse! they always run stock air box with there tunes and setups!

As you can see they run stock air box with RAM Air!

Wait, how do you know that it's stock airboxes under those hoods? In both pics it's completely opaque.

you should be banned for you're stupidity. those cut outs are exactly where the filters on AFTERMARKET air intake filters sit you dumb fuck. and AFTERMARKET is PROVEN to make more HP than stock. how many times do you need to get your butthole flamed until you give up and leave.

When I got my 2011 G37, the dealer did not have a black IPL in stock. So for about $6K or so they put together IPL performance pack for me. It was ECM, Eng cover, body, rear package tray, shocks and springs, wheels would have been more.

So they installed all that for at the dealer, I was happy with that as I wanted black on black and did not care for other colors.

Also just got my car service last week and they updated my ECM and TCM for me so I have the most recent software and eng tune!

I do how ever have to get my plugs replaced at 60K and not 100K like the non IPL does.

Oh wow!! really?? I think you should do more research before you call names and show your true ignorance! :shakes head::shakes head:

Mines even makes there own high flow filters for the stock air box!

I think your just upset because you are trying to justify your intakes! :rolleyes:

Actually, those vents would/do work perfectly with the Stillen Gen3.

Wait...am I still perpetuating this thread??

your mom uses high flow air boxes.

look at the pics you posted then look where aftermarket air filters are.....coincidence?

and you're a troll with this stupidity so i'll call you what i want. :tiphat:

ffs...

that's because amuse is going through rough times and couldn't afford the stillen G3 or G2 or G3.1 or watever those things are called! :mad:

I have own 2006 350Z 2008 350z NISMO 2009 G37 6MT 2010 370z MT sport, 2011 G37

Before that, 2004 Altima, 2002 Max 6MT.

They all had intakes and you know what I ended up going back to stock!

Mines tunes there cars with stock Arirbox and there VX Mines Filters in which are like $385. The CF cutouts you see are like $900.

Mines Motor Sports

Mines even makes a ECM that is tuned for the stock airbox!!!!

Mines whole site is filled with garbage. 1300 for a ECU? you can get a uprev tune for less than half that and get more performance. 380 for air FILTERS? cool bro. and full CAI for 300-500 is a waste for more performance.

OP needs to give it up already haha :facepalm:

Mine's is a status symbol. or shinbaru.

i have Mine's on my rear spoiler so i am cool.
do you have Mine's bit on your car? then not cool enough. :mad:

But we're still clowns for modding our cars. :shakes head: :(

damn guess i'm not cool enough :shakes head:

couldnt disgrace my car with even a mines sticker lol :bowrofl:

perhaps nissan engineered the stock airbox with performance and fuel economy in mind, and aftermarket intakes are engineered with only performance in mind? so it really comes down to your personal taste and needs. neither will be the best solution for everyone.

but the Mine's rear spoiler add-on gives the car super stability at 25mph!!!!!! (per CDepp). never know what i might need to dodge at those speeds.


i am sorry that you could not make the cut. :shakes head:

Its true that Nissan probably has the best design intake and exhaust combo , as on the Nismo, most of it is a marketing ploy to get you to shell out the extra $8K for the Nismo over the base model.

Nissan could have put the same parts on the base model, then no one buys the Nismo.

Nissan's hands are also tied by the EPA regs. Aftermarket companies offer their exhausts and intakes with the usual disclaimer that they are for off road use only or track use.

So the aftermarket companies can pull a few extra hp with open flow thru systems.

If you have an out of warranty Z or bought a used one out of warranty , you could play around a lot with the exhaust and intake system and not really worry about anything.

But with a new car under warranty, I wouldn't want to run the risk of voiding the warranty or having to store an old exhaust system and intake system , that I would have to reinstall if I have to take the car in for a warranty related issue. Its simply not worth the BS.

but the Mine's rear spoiler add-on gives the car super stability at 25mph!!!!!! (per CDepp). never know what i might need to dodge at those speeds but i am ready.

i am sorry that you could not make the cut. :shakes head:

i still am in warranty with intake and exhaust. called the local nissan garage since i need a part replaced and they said no problem. warranty still honored.
