I'm debating whether to get a CAI or short ram intake for my JDM B18c. I plan to keep it stock so I thought maybe go w/ the CAI for more gains? However, I'll lose low ends right? I've had it on a GSR motor and that was the case.

 

you shouldn't really lose any low end with a cold air intake

 

Errr...you may suffer a bit on throttle response with a CAI versus a short-ram. The overall gains more than make up for it however.

I had a short ram for about a week and then went with the CAI and there is a slight, (read miniscule) difference between the two. The CAI does have the edge.

 

any power difference from the stock intake? If so where?

 

On my butt dyno it seems that there is an increase once I hit VTEC and going from 6000 RPM to 8000 RPM is a lot faster.

Disclaimer: My butt dyno may or may not be accurate and the perceived gains may only be in the head of the vehicle owner!

 

what are you expecting out of the intake? i ask you this because i used to have an aem cai and have reverted back to the stock air box.

for one, there is a chance - albeit minor in southern california - of hydrolock (sucking of water into the motor) if there is rain. i was paranoid about this *everytime* it rained and it was not worth it to me. second, you will notice a loss of throttle response in the low end of the rpm range. however, when vtec is engaged/engaging, the gain it slightly noticable.

if you are doing mostly daily driving, then the stock airbox is much better. however, if your r sees a lot of track time, the aem is great.

the veterans over at honda-tech.com seemed to have at one point in time owned a cai and have pretty much gone back to their stock air boxes because of these reasons.

having said all of this, do as you choose ...the aem cai is a great intake; depending on your goal(s).

good luck!

 

I notice a whistling noise when accelerating when using a short ram or CAI. What causes this whistling noise?

 

The conical filter

 

So how do I get rid of this whistling?
