Hello guys,

I know this is a question that has been asked. However, I looked all over only to find semi solid numbers on what to expect. I read a lot of research on CAI, and the benefits of brand names.

According to a few threads on this site i have seen contradicting information on both sides.

I just wanted to know if anyone has solid increase number or dyno papers?

ZZP says that its just as good as CAI, for a fraction of the cost I would be surprised if it doesn't differ by a few whp.

However according to a tune thread I read on another forum, the numbers were inconsistent. However that was from 2009, so I don't know how relevant that is to today's tuning world.

Sooo, any real world gains on the LNF through airbag mod? and if so, any difference in power gains to a CAI. (real world gains through dyno)

Thanks guys for the input!!!

 

i dont think that you will find a specific dyno for the airbox mod on an lnf

if you want dig through the lnf section of the official dyno thread uou moght find something of interest there if you sort through the mod abbreviations

 

Without a tune any mod on the lnf is useless due to the learn down feature.

 

Buy what you want brother. The turbo will suck air in no matter what. You don't need a tune to make the turbo more efficient. People that say you need one for a CAI are morons. You get the same amount of air before/after, but a little faster. And a little easier. So no. No tune for that. You'll be fine. It's not like a N/A car where that little bump in breathability matters alot more. Just go buy the prettiest one and be happy

 

so all the people that have had various issues with stft&ltft on this car after installing a cai are morons huh? and a tune didnt fix it?

 

maf placement and tube size matters for maf sensor readings. thats why you need a tune. going up in diameter of the pipe will slow flow down and the sensor will read less flow or vice versa. if youre in a stock tuned lnf, you really need to get a tune anyways if youre interested in making more power. that should be #1 priority if you want easy power without killing the bank

 

By telephone or not
Forgive me if I did not state this in my original post, yes my current lnf is stock with no tune however I have been contiplating doing the airbox mod with the 3 bar map and tube then along with other mods (3" dp, intercooler with piping, etc) with tune from HP tuners. I was more curious if the box mod and all was a significant less HP to a CAI after tune, as the resources I've read on here have not been consistent on showing true number gains.

 

There is no point to change your sensors to 3 bar sensor, the only reason you would need to do that is if you are boosting over 23psi. I changed my sensors to 3 bar because I wanted to boost 27 psi and it will allow it to read correctly rather than guess what the car is doing.

 

Thanks for the heads up. I am planning on a 23-24 psi tune hence some of the support mods such as ic and piping. That's why I was going to get the 3 bat map. Besides its only like 25 shipped.

 

You need 2 of the 3 bar MAP sensors, and you need to get the adapter connections for it.
1 sensor in on the intake manifold and the other is on the lower charge piping.

I know its more than $25.

 

Also if you're going to be boosting 23-24 psi, get a real intake. It will be a little better flow over stock with airbox mod.

 

Im sure some people will fight you about the flow of the air box mod

 

the "real" intake probaly will flow more air for a short time until the filter gets dirty

point is zzp intake tube plus airbox mod will flow more air than a ko4 can produce hell zzp made like 380 with it

with the sri or cai your buying something shiny and noisy that requires you spend more money on a tune, most people will get them but you dont have to for performance reasons

 

I prefer my modded air box/K&N panel filter/ZZP intake tube over other LNFs that I've tuned (V2 AEM, Injen, K&N SRI).

Sure, the BPV noise is cool but there's no difference in power and the fueling is much easier to keep in line due to much less turbulence across the MAF. off-idle IATs are slightly better as well.

FWIW, I have a copy of a dyno sheet from a bolt on LNF that picked up anywhere from 8-12whp throughout the curve from about 4500RPM to 6500 by just adding a ZZP intake tube to his modded air box. You can search for it in the dyno section too. All said and done, I'd estimate a modded air box/K&N filter/ZZP intake tube picks up 12-15whp just like a cold air/SRI will

 

I'm interested in this too. What I'd really like to know is if there's any noticeable gains from doing the airbox mod + ZZP intake tube + stock air filter. I'm not a big fan of K&N filters, I think there are some good reasons why OEM air filters are engineered the way they are.

Also wondering if there's much benefit in doing any of this on a car with a very mild tune, or if it's only worthwhile with something more aggressive.

 

I just recently put in the K&N and there wasn't any noticeable difference from a clean OE paper filter. However, it was BNITB and free.

Again, 12-15whp on a tuned car. The aggressiveness of the cal doesn't matter. Have you seen what the stock accordion intake tube looks like?

Bottom line, do it.

 

bumping an old thread. does anyone have pictures on how to mod the airbox for a t/c?

i saw this thread https://www.cobaltss.net/forums/2-0l...ox-mod-163744/

but the pictures are dead links

 

It is a pretty simple procedure honestly. Remove the airbox with the filter in it, then remove front bumper to get to the snorkle. Cut the snorkle at the wide portion as it begins to taper down. Then cut the bended tube part at the end of the snorkle attatch a silicone attachment the two parts together. place the box back in, and buy the upgraded intake hose from ZZP... tada, its not to difficult However considering I like the pst noise without ricing my car out with a BOV I choose to go with a K&N SRI

 

You can get the noise with an aftermarket BPV and it sounds really good. I have air box mod and I think it sounds good with the Forged BPV
