I have a 89 civic hatch that I removed the little black plastic tube going from the airbox to the back of the radiator and the one going into the fender.
I was trying to allow alittle more unrestricted air into the airbox.
my question is to all of you that have CAI , is this .......
Do you actually see a difference in throttle response or HP with the standard CAI system or is jsut sucking up hot air?

 

You can get some pretty good gains from a CAI setup if it's well designed. Especially on a high revving engine that flows very well. Stock airboxes are designed to quiet down the intake and aid low end torque rather than high end, IMO. I'm surprised they don't offer heat shields with all of these Honda CAI kits that are on the market. I mean the headers are right next to the filter.

 

So in all honesty , it sounds like if your not racing , where you primarily drive at higher rpms, and are daily driver that the stock setup is better?

hmmm don't we all drive at high RPM? =P I thought this was Honda Tech, j/k. I noticed these engines make peak power typically above 7000 RPM. That's a lot of revs but these engines are designed for it. The gearing is also very short to match the high revving characteristics of the engine. Cruising on the freeway the engine is already buzzing along at 3500-4500 RPM which is relatively high. I would definately go shielded CAI as the stock setup probably doesn't flow enough air and the added low end you'd get from a stock setup wouldn't be missed anyway since low end torque isn't what the engine is about. Once you get going it's all mid to high RPM.

 

I agree , these engines do have most of there torque in the top end.
As I said before I am new to hondas , so where are the shift points , at normal driving , in a 4 spd manual?

 

i gutted my stock air box lol, by cuting where the small hole was and made it bigger. yes i know that so ghetto rolf

 

cold air is the only way to go.

 

does a cai or short ram intake make the engine sound cooler too? which one better? lol
