WHY OEM INTAKES and FILTERS ARE BETTER

UNKNOWN_370

I don't know why the OP is borderline being flamed because he is right...

At least when we are talking about only installing the intake. The intake can increase gas mileage in a car based on his explanation of how power re-distributes once the intake is installed.

But what OP is also failing to realize that anyone putting on an intake ONLY and thinks they improved the cars performance is dilusional and is feeling the euphorium placebo effect from buying something shiny on their car they can show off to their nut-hugging friends... You wont see any power gains till you are somewhere around 5200 rpm. Anything else, you are losing between 4 and 12rwhp.

So why do we install intakes? Intakes are there because they are part of a system. That system is a new intake, manifold, header, downpipe/HFC, and exhaust. when you make the complete mod and finalize it with a tune, you will see serious power gains. Between 50-80hp.

Most don't follow this method. Most add on an intake and exhaust. Forget about the rest and at best gain 20hp up high while losing 10 down low. The full mod is meant to be done in one giant modification to feel the true results of your breather mods and tune.

Is buying an intake over stock worth it??? Fvck NO!!!

Is buying intake, manifold, headers, downpipe/hfc, exhaust and a tune worth it.. FVCK YES.

Then there is another debate... Which intake companies design intake that will lose the least hp down low before gaining. This research would be very costly because it would take a well financed magazine to go throw every type of intake and dyno them.

What may be great engineered intake on one car may not work as well on another. Theoretical Example. Stillen may provide 18hp above 5200rpm on th Z but it may lose 12hp from 1000-4800rpm, while injen may only produce 15hp above 5200 rpm but injen may only lose 4hp between 1000-4800 rpm??? So which mod would be better?

I don't think anyone has tried to do direct dyno comparisons but it would be good to see the effect with equally modded cars.

Exactly. This inevitable response should have been on page 1.

My favorite is when people claim better fuel economy after an intake install...

what everyone fails to take into consideration though that while yes, the intake by itself may not provide big gains is the fact that not everyone can afford to plop down the 3 or 4 grand it would take to do all of the above that you mentioned so while it may not be worth it to some people to get just the intake, other people view it as a first step to a larger goal till they can afford the next piece of the puzzle so to speak. in any case this is just an opinion thread so there is no right answer when it comes to this topic, people are just going to do things the way they want/are able to do within their means.

Here are multiple results from multiple companies showing... well, results better than 4-6whp and more than just 6.5k+

Not letting me link MotoIQ, but google Moto IQ AEM intake results and they have a good write up.

So you refuse to answer a simple question useless someone pays you ! (WTF)

You can't explain your own dyno posting, makes no sense !!!

Also look at the most of the dyno charts you provide, pretty much the same baseline HP and Torque curve for most of the charts until 6500 RPM. Like I said how often are you are going be driving between 6500 and 7500 RPM.

The other charts you provide only show a better torque and hp curve when the exhaust is also changed.

SS_Firehawk

what is there to explain? When the install happened, NST pulleys and AEM CAI's were installed at the same time. If you are so eager to figure it out, Call GTM and have them put my car back together. Seriously, what is it that you don't understand?

Oh might join the band wagon...Op I do agree with your statement the OEM is probably as good or better than any aftermarket intakes.
Did I feel any difference in performance? Certainly not...
Do I want to push my Z hard? Certainly Yes...That is why I bought a sports car.
Do I care about gas consumption on my Z? Hell NO... Gas is more cheaper than PROZAC or ZOLOFT!!!!
Do I care about performance numbers? Probably Yes and NO
Just like Firehawk have said Modding is not like 1+1=2, sometimes you even end up with Zero or negative.
But the beauty about modding your car is not entirely because of numbers or performance alone but its also a "Feel Good Commodity".

One good example is the Sports lightweight rays wheels. These are probably the BEST wheels out there in terms of performance both in the street or in the track but why people over here like me had to change wheels?
Its sad that these high performance wheels are only selling 1K at the forum ADs....It doesn't make sense right?
In fact I made my car even slower by having a 305 tire set up in the rears on my M10 wheels which is far heavier than the sport rays.

Did I stupidly spend my hard earned money in buying my K&N typhoon filters knowing the OEM filters works better at certain extent? I would say NO...As I enjoy every minute of it seeing it inside my engine bay. To me its a worth while investment because I am "HAPPY" with it.

Modding is an ADDICTION just like any sin.... Is buying a Rolex watch better than buying a Timex watch?....As far as I know both give me the same time...
I rest my case.

Fsckng lols. ^^^ this.

You sir, owe us all ice cream. This thread has reached greater than four pages.

I'll take some delicious chocolate and vanilla. Two scoops of each.

To op:

Why wear different clothes when it is far more efficient to have a something like a military uniform with pockets. Its long sleeve, covers your legs. Pretty good in every weather, and would save us billions in production (instead of designers/labels).

Why eat different food when we could all eat the same meal from one restaurant/provider. Costs in shipping and man power would be cut by billions. You would never have to ask your date "so where do you want to eat". Save costs and headaches, how great.

***Sarcasm aside, yes this is really how simple this is. We love it. That goes for mods in general.

*** To the Intake statements: Open all restricted airflow with breather mods and tune as previously stated. Sound, power, efficiency and butt dyno (the only thing that matters) dramatically improve

I won't waste my breath, no one here cares about facts and engineering...

I just want my ice cream.



Though, the butt dyno is really what matters most (as said before, but I just like the term "butt dyno").

Give it enough time, our current administration will have us doing just that.
