just put my koyo n flo in, and found out i cant use the stock
intake...wish koyo would of told me that, i would have gotten the corksport rad, also my stock shourd dosen't fir anymore...

but yea i wanted to know if they were any carb legal intake filers on the market anymore, i know of the hks one but i cant find the older version with the carb sticker, only the new reloaded product but i believe it lacks a carb cert

 

it all should fit with a little dremel work.

 

I have a S4 Koyo in my S5 Auto Vert (don't ask) with no issues about the stock intake.

I have an S5 Koyo in my S4 TurboVert (don't ask) with no issues about the stock intake.

I have an N Pass in my S5 TurboVert and only mod was to the stock fan shroud. Nothing about the stock air box.

Pictures and maybe someone can help as that being a problem is curious as best.

That said, K&N still makes the Carb legal intake.

 

Are you in CA? This isn't an issue that I have ever had to deal with. I'm pretty sure with a little "fabbing" you can get the stock intake to work. Any pics of the issues with fitting the radiator and stock intake in that you can show us?

 

alright i'll take picture's tmr

fyi the s5 nflow dosen't have that long filler neck for the rad like the s4 does

so the stock intake piping ends up sitting on the shortened filler neck on the s5, so you can't really bolt it down or install it properly for that matter

but you guys dodged my question =/

 

Dodged the question? Not intentionally. I think very few people actually deal with CARB on a FC intake. In WA there is just a sniffer test, no visual. I have never thought about CARB in the last decade of owning a FC. I even get around the sniffer test by registering outside the 3 counties around seattle.... no emissions what so ever.

Rather than buying a CARB intake the majority of people think you can just get the rad to work with the stock box if you provide us some pics and the issues you are running into installing it.

 

but maybe I'm just looking for an excuse to upgrade, I have a blitz lm filter but I got dinged for it

but yea picture's comming soon

your lucky bro, in CA we have smog ****'s and i swear man it feels like cali hates turbo rotary engines

 

Can't you just take it on and off for emissions? It's just and intake. 10 minutes to swap to stock?

 

the intake piping on both S4 and S5 is the same, there is no question ask unless your intake box is sitting where your fender should be... the only difference is the rubber adapter to the airbox moves the piping back about half an inch on the S5 because the airbox is slightly different.

something isn't sitting right in your setup, as said many times already the koyo's bolt in fine with a little cutting to the fan shroud, that's pretty much it.

 

Go on ebay and pick up a HKS intake or buy a new HKS intake, those are carb. If you go the 2nd hand route, than go to the carb website and find the corresponding paperwork/carb number for it and keep a print out of it in your glove box, thats what I did.

I think Apexi also made a carb legal kit, i forget.

K&N doesn't make a carb legal kit for Turbo application.

http://www.arb.ca.gov/msprog/aftermk...es/amquery.php
Than under executive order, search air filter/intake modification, then use your web browsers find tool to look for rx7. You will see all the kits made for it.

 

yea but the problem is hypertek I'm having a hard time finding carb legal intakes, I've found the hks one but then I ran into another problem...it doesn't say if it's for turbo or n/a applications so it gets kind of confusing (I don't want to buy the wrong one)

and I haven't had anyone verify if it has some kind of sticker on the intake so the cops have something to go off, I've been told that piece of paper doesn't mean ****

 

I can't swap it in 10 mins when chp tells me to pop my hood =/, because I look like i'm highly modified or some bs

 

yea, in cali most authorities won't take a piece of paper. the japanese never added carb labels because it isn't a big deal to them, even if it truly doesn't make a carb legal product carb legal in cali. most smog shops will accept the paperwork, most cops and even some referees will not.

the only legal filter mod i know of is the stock air box K+N filter which really doesn't make **** worth of difference. you can however mod the airbox so long as it is there. it still should fit fine with the koyo.

 

You could do what I did for a while, I have a cut out airbox lid that I used to fit over the hks intake. lol



But i took it off now, so far my car doesn't even get a second look from cops. They usually won't think twice about clean cars unless they are loud and or look like ****.

 

refers back to the issue of why the stock airbox won't fit in the first place, which would end any further questions or concerns about it. only takes 20 seconds to swap the stock airbox to fix the issue, so long as it fits. that is funny though, lol. what's funnier is a cali cop would write you a ref ticket for the blue silicone radiator hose and yellow top battery! modified cars, you must be a street racer!

 

Any update on what you've done so far? I have this same issue after installing my koyorad...

 

I'm switching over to the hks intake kit, it's carb legal and comes with the sticker, called HKS USA myself to make sure before I blow 160 on the kit

cheapest place I found the kit is on amazon around 160 shipped plus no taxes

 

oh btw krack if you could use hypertek's picture for a reference,

he has a s4 koyo radiator, the s5 koyo the rad cap sits on the radiator itself,

it dosen't have that long neck you need so the stock intake piping can sit properly...(the stock s5 rad has the long neck, but for some reason the s5 koyo rad doesn't wtf koyo!!)
