Cold Air Intake for GSi

[act_gooner]

Hey everybody,

I'm looking at buying a CAI for my gsi, probs Injen. Just wonderring what the difference is between the DC4 CAI and the Vti-r CAI because I noticed that in the JDM Yard section on here they only have the Vti-r part for sale, not the DC4... Are they practically the same thing? Probably being a mad n00b I just want to make sure that if I was to buy the Vti-r CAI it would fit properly and I wouldn't have any power losses.

Thanks y'all.

VTi-R (B18C2) has an 'inverted' intake manifold so the throttle body sits lower and you get fitment issues with DC4 or DC2R intakes.

B18C2 (observe the intake manifold where you can see the plenums curved upwards)


Type R engines and B16A's are like this (see the angle is reversed):



So I don't believe it will fit the DC4. But the Type R intakes should fit.


Get a Fujita intake or something I think, not an Injen. Or even an ebay intake will do the job.


This one looks like it will fit.

Just change the air filter to a Fujita or 3A Racing one or similar.

dc2r intake will fit!
or just do a diy cai

Well I currently have a K&N pod filter but want to upgrade to a fully intake system. I have heard that the ebay ones can cause problems because they are cheap so I'm willing to pay a little extra for something of real good quality. Is it your bro that has the DC4?

Am I likely to lose power with the dc2r intake? That would be the last thing I want for the gsi lol.

So you already have a short ram intake?

Ebay filters I would not bother with, but otherwise pipe is just pipe. I can't see how ebay pipe would cause damage just because they're cheap - think of it like this: They're cheap because they're not ripping you a new a-hole by making you pay $300-400 for what is effectively some pretty packaging.

So like I said, you can use cheap pipe with a good filter. Same sh!t as the $400 intake.


My brother has a DC4 and we're using a generic CAI. Still functions fine.

He's saying that the OEM or any after-market DC2R intake will fit. They will all give you power.

I just stuck a Pod filter on the stock pipe. What about SIMOTA? Surely Injen will give me a bigger power gain which would be why its so much more expensive?

No for the love of God they won't. Don't just go buying sh!t because it's more expensive. If you feel that way just get a Mugen intake for $700+ or whatever.

Sometimes people just rip you off and you'll get the same results for much less money.

Personally I'd take any cheap ebay piping with a good pod filter over a full AEM/Simota/Injen intake because they're just too expensive.


EDIT: And you probably won't notice a huge power gain, maybe just a little better acceleration or it feels like it's rev'ing up more easily. Lots of noise too. Some of the big-brands claim to make an extra 4KW which is all very nice. But for sure you wouldn't be able to tell the power difference between a $100 CAI and a $400 CAI, provided you've used a good filter. For that use Fujita or 3A Racing like I said earlier.

Alright thanks man. Was just trying to see how the high price is justified as a lot of people seem to buy it and reccommend it. I have more options now so thanks for the help.

Yeah sorry if I got passionate there lol. The one true benefit of an expensive/branded intake is that it's going to fit perfect most of the time, but lots of ebay products are just as good for this.

Also a lot of people probably just don't trust cheaper options simply because they're cheap.

If you can find a second hand Injen for a reasonable price like $150-200 then I would consider it.

Otherwise it's just like shoes. Why get that cheap pair when you can get a set of Nike's? They're the same, except one has a 'tick' stitched onto the side by some 12 year old in China or something. Yet they're 4x the price?


I made my own Civic CAI. I bought a cheap APC short ram intake for $70, then used some Super Cheap Auto rubber and aluminium pipe to extend it into my bumper. Cost another $105, so $175 total.





As you can see I also got a header - $199 brand new, ceramic coated. Great craftsmanship too, but without the price tag!

Lol shii your a mad price saver. I'll have to see how I go, when it comes to manual labour I might as well be a woman because I'm ****ing terrible at it haha! So I'll probs be looking for an easy option. Maybe second hand or ebay.
