There is a K&N unit for sale on Ebay at the moment, it has just under 3 days left. It is same as the one I fitted to mine. If you are interested in doing this I have a 45° bend silicone tube spare with a jubilee clip to fasten it which I can sell for a cheap price. This option is for the 1.3 engine. I can give you tips on fitting it and how to connect the temperature sensor. The filter has a great place for this. You would only need to make a small bracket to support the filter housing and a longer bolt to attach them. Take a look at my photos I posted. It might be worth it if the price doesn't go too high. http://www.ebay.co.uk/itm/K-N-Apollo-Kit-Universal-Cold-Air-Intake-Filter-RC-5052AB-Supra-Skyline-WRX-STI-/221264323757?pt=UK_CarsParts_Vehicles_CarParts_SM&fits=Model%3AS2000&hash=item338461a4ad
Looks a bit big to fit in the space for the turbo version. Lots of information for the turbo induction here: https://www.copenworld.com/vb3/showthread.php?t=1555&highlight=induction
Hi trustafox, did the air intake work? I am also thinking of modifying my intake but I am not sure which one would be the best option for 1.3. I know there are many solutions available for 660 though..
Hi jaspark, What do you mean by "work"? Does it suck air in, filter it and move into the combustion chambers, then yes it does it well enough. Does it give me whiplash now when I put my foot down, then no it doesn't. But its never going to with an 85 hp engine. My aim was a small tweak and possible commutative with any future upgrades (exhaust). Also it was so I didn't have to keep source the standard air filter which isn't cheap either. If you want to add a bit of deeper throaty roar as you accelerate , then yes it does that if you leave the cold air feed off. I just find it out by the fact mine slips off with the vibration over time as its not securely fixed to the inlet of the air filter housing . But I have a change/remedy/slight upgrade for this issue coming in the post. And when I mean slight, I mean microscopic But it will make me happier knowing that. So to get some noise if thats your bad then just leave the pipe off. I know the cold air feed people will come saying you be loosing HP sucking in the warm air in the engine compartment. But come on how much of 85 HP are we going to loose or not gain. Again my neck doesn't hurt. So if you do get 0.5 HP at 6000 rpm because of cold air would you ever notice it? A Scooby turbo might get you a small fist full of dollars.....HP, but thats putting out 4 times the power and using pressurised air that gets hot. On the plus side it does give a more sporty look under the bonnet. It may give a slightly better throttle response though as I've tried to get a smoother air passage that that rubber concertina thing. The problem that remains is that crappy bit of plastic channelling that looks like Tyson used it as a punch bag. I've spent half my copen ownership hours scratching my head over that bit. PS there isn't a specific one for the Copen 1.3, mostly because Japan never used that engine. I don't know if they ever did one in Germany. Have you seen the photos of mine?
Thanks for the response trustafox. I was actually thinking of modifying it not for extra power but a bit noisy air intake. I agree with you that how many bourse can we really get just by changing the air filter. Just a bit of noisy intake will satisfy me I guess
bourse? If you went with my set up and no cold air feed pipe you get quite a nice bit of induction noise. Its not over noisy either and quite a meaty sound, not high pitched like a hoover. Also when cruising you don't hear it, so can just get the thrill of it when you putting pedal to metal.
Bourse-> horses sorry That would be great if you could email me your sound file. It's jaspark@hotmail.com Thanks
Hi trustafox, since you are an expert and have played around with air filter mods maybe you can help me with this. I am a newbie - you can tell that, right - with a 660cc turbo however the air filter box is missing the cold air intake pipe to the back of it, which might make good induction noise but it has the side effect of the air filter getting a black oily square on it because greasy air gets pulled through the square hole off the slightly greasy block area. Hmm, I think I'd rather fit a cold air pipe and save air filters. Anyone got an unused cold air pipe for a 660cc turbo? I'm in Australia by the way but postage would be less than buying a whole air filter box assembly at $hugely expensive (the happy parts man said).
Hi ticcy, I don't have the turbo engine but the big boy's 1.3. The air filter assembly is totally different and location is different. I don't have any experience with the turbo set up to give you much advice. There are a couple of posts by turbo owners that have modified theirs.
