HKS Rs intakes
really depends on the weather. colder temps create less pressure which makes the car run better and more efficient. which in turn, creates boost spikes if the air entering the intakes is cool enough, which is never good. if thats the only flow mod you want to do at this time, then you should be fine, just keep the fd in the garage on those cold nights.
with you being in virginia the temp outside is cool this time of season. you can put the intakes on your car, no problem. just done take it to WOT and you'll be ok till you get everything else done(new computer or boost controller that is..)
What's an HKS RS intake? Is that the same as the HKS Super Mega Flow intake?
Anyway, you can open the intake on an FD with the stock ECU, the real problem is changing the intercooler and/or main cat on the stock ECU.
Also, be careful with FD intakes. Most aftermarket intakes suck up more hot air than cold, which is one of the ways engines can blow.

The Super megaflow is cast pipes, the RS = Racing Suction is polished aluminum pipes. Same configuration just different piping and filter cage.
You should have no problem with the RS intake. Just be sure to re-attach all your recirc hoses to the new intake

hey those do look nice, but to me(a noob) it looks like they would be close to useless because they suck in hot engine air. i see the short rams on fd's constantly why is this? does the heat in the wankel vent some other way? i mean you have turbos or at least a turbo, and a not to mention the beast down there? so why have an intake near all that stuff? no room is my guess. but correct me please.

flow mods cause spikes, and 3 seem to be pushing it with how people drive fd's
Looks identical to the SMF that's on my car other than the cast vs the aluminum. I assumed they were the same spec as HKS didn't say otherwise from what I recall. I apologize for the supposed false information

Cold air intakes aren't as important on a turbo charged car as on a N/A car. On a N/A car, the air just goes straight into the engine. With a turbo-charged car, the air is going to get super-heated by the turbo (even worse with the stock twin infernos on the FD) and then cooled by the intercooler. You'll get far better charge temps with a good intercooler than you will with just a cold air intake on a turbo-charged car.
so im still a noobie right, but why arent NA cars intercooled. I dont know exactly how that would work but im guessing you just find a way to attach an the intercooler piping before intake and on the TB. but would that even make a noticable difference because its just the same amount of air and just colder? or would it bog things down because of the ic. thanks for the help mahjik
i.e. if you are taking in 70F temp air, and then trying to use 70F temp air to cool it, its not going to get any cooler. When air goes through a turbo, the air is compressed thus heated. So on a turbo-charged car, when you take in 70F, its going to come out of the turbo much hotter. Therefore, you use the ambient air (or other means) to cool it back down as much as you can, before it goes into the engine.

The intercooler is using ambient air to cool the charged air. Your intake is taking in ambient air. So, if you are taking in ambient air, you aren't going to cool it any less than ambient temp using ambient air to cool it.

ah i had no idea the intercooler contains ambient air. thanks for all the help
ok wow now im learning something, so the ic attatches to the exhasut manifold and the turbine housing. spins the turbine which spins the compressor, so now i see how boost lag is created, the time it takes for the used air to get through the turbo and to the engine from the ic. so how important is it to have a less restrictive yet effective ic? can ic create boost lag? oh and how necessary are intakes, i mean sure you are going to need a less restrictive air intake to get to the spooling faster because the turbo relies on exhaust gases. but really how much air does it intake after the whole process of the turbocharger because in theory couldnt the turbo reuse all the air if you have a nice intercooler?

The intercooler doesn't contain ambient air...
When air is pressurized, it heats up. If you've ever played paintball and used a nitrogen tank, you'd notice that immediately after the refill, the tank gets very hot. The same thing happens after a turbo compresses air. In an attempt to get the air temperature as low as possible before entering the engine, the intercooler is installed. The hot air is INSIDE the intercooler, and the ambient air passes THROUGH the fins, and out of the back of the intercooler. At no point does the ambient air go INSIDE the intercooler.
