who makes a cold air intake for a 00 civic si that has 3" tubing?
i can only seem to find them with 2.5" and that nowhere big enough for a 72mm throttle body

 

you can either use a 3" AEM type R CAI or an Aem Hybrid 3" cai.

 

so the acura integra type r intake is direct fit?

 

yes, I believe you have an EM1 right?

 

correct sir!
if that is the case will the comptech induction box and such fit also?

 

The AEM hybrids are not carb legal in CA>FYI

 

I do believe so.

 

If your not woorried about barring search ebay title and descriptions for " 3" intake civic". And why do you want the cold air?

 

i wont buy ebay garbage...i want a "cold air" intake due to the fact that short rams suck hot air from the engine compartment from right behind the radiator...who ever thought that was a good idea needs to be shot.

 

The AEM type r intake is not "direct fit." People say that on here but its not. I had that intake on my EK with gsr w/ skunk2 manifold and it does fit but you have to cut it and shorten it and it won't sit straight. You gotta play with it a little make it fit. Honestly those ebay intakes arn't bad tho for how little they cost. That with a good K&N filter and proper placement would make good hp. Just make sure it sits far enough away from the radiator

 

oh wow....found what i was looking for finally.

anyone have anything to say good or bad about this setup ?

 

Its looks like a decent piece but consider the price on both items. Its a little pricey. Might as well just get an aem. Personally I would get the hybrid intake since they don't have a carb legal 3" intake for an SI and you seem to have performance in mind. But if you get this product let us know how well it works.

 

Why pay for the hefty price if it isn't carb legal? I would personally borrow someones for tuning purposes and just custom made/ebay it for yourself. I'm in the same situation so report back with your final outcome.

 

AEM 3" ITR COLD AIR FITS IN THE EM1 SI BODY CIVICS

 

^^^I was referring to AEM but from those links, I personally would get the icebox and it doesn't come with a filter.

 

do what ever u want...

 

I was referring to my own post. I was just saying why spend the money if it's NOT CARB LEGAL!

 

Actually it says its carb legal on the web site. I would check the BAR database tho to make sure but they claim it is.

# Must be used with the CT Engineering Intake Kit
# CARB legal
# Application: 99-00 Honda Civic Si
# Installation time: 1.5 hours +/-

lol 1.5 hrs to install an intake.

 

The pipe is just a pipe. Its the filter that matters. And by the way, ever wonder why all these nice dyno plots on here have short rams? I suggest you do a little more research. And if you are worried about heat, get yourself a sheet of aluminum from home depot/lowes and bend it to fit around the filter. Use a circle saw to cut the hole. And if you want to get fancy, you can weld the edges to sort of create an open" box" around the filter. Cold airs are all hype.

In the end its your car. But a cold air kit would never come within a mile of being on my car. I learned my lesson almost a decade ago when I sucked water in and ruined my fresh, built for turbo, b20.

 

cold air pipes are not all hype, just ask B19coupe (if he even comes on here anymore) or Guillotine or most anyone else whose spent time on a dyno testing intakes like myself. The CAI beats the SRI everytime because of it's length. It's not about the filter and it's not totally about the cooler air that it draws (although it is a factor). During testing on a dyno and track, the best intake is a custom tuned one that you fabricate using the dyno. The next best was the CAI and then the SRI at the end everytime. The Comptech Ice Box and Mugen intakes do quite well and usually beat the SRi's and rival the CAI's in many cases.

A SRi is really only good from a packaging point of view and cost. It will prevent any chance of hydrolock as well for those people that are concerned about it. I have used a CAI on my car for the last 10 years without any issues and I live in an area where it rains a lot. Most people that have hydrolock issues remove their splash shields and/or drive in water that's far deeper than it should be.

 

Yes tuned length is the way to go. But I disagree on the out of the box cold air kits which is what we were talking about. There is also plenty of evidence to back up the sri being better theory. And when I was referring to the filter being most important, I was referencing the ebay kit vs aem. Differnce is the filter that's it. You can go to k&n's website and get any filter you want in the proper diameter.

 

I have yet to see (or experience) any theory or reality of an SRI being superior to a CAI in any performance category, on this site, the race track or dyno testing that I've been involved with. For reference, I use to own a performance shop and we tested a number of these intakes out on the Dynojet next door, on many customer cars including my own. I agree that a K&N filter is better than most of the ebay generic filters go. A Ractive cold air copy of an AEM cold air will dyno identical numbers with a K&N filter added to it.

 

Additionally, the difference in air temps between a cold air and a shorter pipe is only maybe 2-3 degrees tops, if you have the ability to datalog you'll see this. And even then it doesn't matter wants it reaches the warmer intake runners. Its really the length of the tubing as well as the diameter and bends that affect the intake velocity which has a greater ability to affect power. And there's a few threads on here that demonstrate this. But do what you want. I tried to help but we have different opinions on this. Sorry I couldn't help more.

 

Just did a quick search in google and there are actually dyno plots to support both our arguments. I searched for "cai vs. Sri honda" plenty of results. Regardless, dyno numbers mean squat. Its track numbers that are the real judge. Additionally, the warmer it is outside, the less effect a cai will have on reducing the air temp of the incoming charge. As I said before its really the length and diameter that have an affect because they affect velocity like playing with runner length/diameter on custom manifolds. This is part of the reason velocity stacks exist and make power. I guess the other way you might see a difference is manifold pressure when datalogging the map sensor. My setup actually hits 1 psi column....lol.

 

your going to compare a car sitting on a dyno with the hood up and big blowers moving a ton of air to a car actually moving on the road with the hood closed? apples to oranges....ive seen comparisons of time attack cars running laps with cold air vs short ram and in the real world the short ram loses every time.

fyi the reason why i like the setup from CT is it acts as a ram air setup

"I learned my lesson almost a decade ago when I sucked water in and ruined my fresh, built for turbo, b20." LOL...this isnt my daily driver this is a track car.
