which one of these are better intake systems? hks kansai carbon air box or hks racing suction kit?

 

HKS Suction Kit

 

HKS Kansai Carbon Air Box

 

Neither, the stock intake is the best.

 

hks rs intake kit

 

i have the HKS..

 

HKS what? RS or the air box

 

Al has had good results with the HKS RSC, according to what he told me.
I'm happy with mine. You deffinitely have to have some type of fuel controller, it throws the MAS way off.
My datalogger shows 33-36lbs of airflow with it at redline (7800).

 

Hmmmm...HKS Suction is an air filter! .....while HKS Kansai box is only Cold Air Intake BOX!..... The two can be combine together hmmm....

 

I like my Apexi Power intake.

 

wait you can put the hks intake with the kansai air box? what about the apexi with kansai air box?

 

Hi,

By all means I am not trying to sound cocky but I wish to express my most accurate opinion about the Air intakes.

With my current 2 cars(EVO MR and 91 Eclipse GSX Turbo) I owned a total of 10 turbo cars in the past:
86 Dodge Colt Turbo
88 Renault 5 Turbo(when I was in Spain)
89 Renautl 5 Turbo (When I was in UK)
89 Renault 21 Turbo (When I was in UK)
90 Plymouth laser rs Turbo (upgraded to a Big 16G)
90 Eclipse GSX turbo
91 Eclipse GSX Turbo upgraded to a EVO III turbo(big 16 G)
91 Dodge Stealth Turbo (Upgraded to two 13G's)
03 Impreza WRX turbo upgrade to a Forced Performance18G
05 EVO MR Turbo

I think that there is nothing called "Cold Air Intake" when you refer to an air intake. Yes , the air is colder because is sucked into the turbo from a colder, further and normally lower and isolated location but think twice, the air then gets sucked into the turbo so it gets heat up, then is sent to the piping, intercooler and finally makes its way to the manifold intake and into the engine.

My point is, the cold air sucked by a Cold air intake is ultimately going to be heat up (Turbo) then cool down(Intercooler) then heat up a little bit because of the piping inside the engine bay between the intercooler and the intake manifold.


I am not a scientist but I have some common sense and I think that when you look for a air intake you should be looking for the less restrictive one, the one that has the best piping diameter, the one that has the best filtering material and best piping design.

On a non turbo car yes, I will have to say Cold air intake will make a bigger difference but on a turbo car it really does not matter much becasue of what I mentioned before.

By the way, I have a Power Agency Short Air intake. This filter is very affordable and uses a K&N filter cone with a aluminium MAF frame. You can see it on Vividracing website.

My .50 cents

 

Why might that be??

 

For the money, Injen intake with upper ic pipe.

 

few things, first off the kansai box is just a box, you have to have an intake inside of it, so take your pick, and hope it fits, hks rs does fit for sure.

there is a such thing as cold air. when you suck in hot air from the engine bay, it is less dense, this in turn getting heated up (or not) and then getting compressed (heated again), gives you less air at some given pressure.

cold air that is taken in is more dense, and when heated up (even if it is heated up to the same temp as the hot air, the fact that it was more dense to begin with just gives you more pressure which is in acutality also more air) will be a little less dense after that fact, but since it started cold maintains denser than hot air status which nets you more air at that given pressure but most likely produces the situation where you get more pressure becuase the more air expanded.

things to keep in mind:
your intercooler only cools to ambient temperature at most.
your cold side of the turbo is not a source of infinite heat, nor is it a perfect or even a good conductor because it's the cold side, the cold side is cold.
the compression of the air also heats it.

this is all theory and wonderful but just think about a cold day, cold days will always raise your boost and always make you more power. now imagine a hot day (the inside of your engine) and you're always pulling in cold day air (cold air intake), more boost, more power.
