Shorter or Longer CAI more effect?

[Seanboi]

Wish to noe which CAI gives the most effect. Is it longer or shorter?

[Elfenstar]

Makes no difference unless the filter is at the end of it. The important bit is the distance from the filter to the TB. The shorter the better.

oic. noted.

so u mean Filter which is further away from the TB is less effective compare to filter nearer to TB???

[Elfenstar]

yup. it equals to using a narrower piping = more restriction. same thing with more bends.

[Turbonetics]

but i felt that my AEM CAI is pretty good...

the filter is located at the bumper area...:)

i tot it was this way that more cold air cld be draw....

[Elfenstar]

hey if more air is getting though the piping than the TB and inlet manifold can take in, who cares But if your TB has say a 3inch diameter and the long piping is 3inch in diameter, you'll find that the car will be able to breath easier with a bigger diameter pipe. why do you think that the original intake piping between the filter and TB is bigger than the diameter of the TB. not to mention its always very short.

This is the typical CAI vs Short RAM intake question

[Wolverine]

Some dude did a test:

 

Cold-air intakes vs. short ram intakes....this is one of those eternal topics like sc vs. turbo.

 

Being the scientist that I am, I decided to do my own test. And being the good guy that I am, I'm gonna share my results with you lucky people :zzz:

 

- With my cold air extension, my intake temperature rises to about 180F (82.2C) after some very aggressive acceleration. With just the SRI, my intake temp rises to about 193F ( 89.4C) after some similar driving.

 

- Cruising intake temp is around 146-148F (63-64C) with the CAI and 148-152F (64-67C) with the SRI.

 

- Both types of intakes take about the same amount of time to reach the max intake temp and the same amount of time (about 11-12 sec) to fall back to cruising temp (about 1 min).

 

- This is was all done with the outside temp being 54-55F (13C).

 

- Intake temp was measured with the intake air temp sensor on the intake manifold (courtesy of Honda) and was recorded with Hondata datalogging.

 

- Note that this was done with and Injen 3" intake on a supercharged integra so your results may vary :angel:
