Does one even NEED an intake?

As some may have noticed, I have posted several topics relating to intakes in some way or another...

well this is because I don't want to send X dollars without knowing if it's worth it (as I am sure many understand)

If I am going to be running a PROcede Rev2, and other than that, I don't see myself getting an exhaust or downpipes (at least not in the near future)

so... would I even need to change from the stock intake? (whether it be injen afe stett etc)

Thank you and sorry for being such a nuisance :P

If looks and sound are important to you, then yes, a dual cone or cold air induction will help. Performance-wise, it's debatable. Similar results have been achieved with both a high-flow drop in filter, dual cones, and CAI.

In any car that I have had, I have rarely opened the hood.. so looks is not an issue...

performance gain (like hp gain) not that big of an issue as much as allowing my engine to run without (or less) problems due to increased air flow.
but if the stock one is enough or more than enough.. then much of a point in that area

sound is nice, but is it worth a 170/280 dollars? debatable... I'd rather get a smarttop if sound is the only thing...

its just that my car runs at an avg of 240 degrees even without a procede so i'm scared that it'll run much hotter when I do install it...

An intake won't affect that. What you need is an upgraded front mounted intercooler.

dude, you've already made up your mind that intake isn't worth it. so why do you keep asking us to convince you otherwise if you aren't taking anything we say seriously.

An intake will not help you with the oil temps. If that's what you're worried about, save your money and put it towards an upgraded oil cooler.

If i had decided, life would have been easier :/
yet, i cant complain that the main questions on my mind now are what to do and what not to do and what should i do etc regarding my (already amazing) car....

Thank you all for the information

Intercooler does make the most sense.
I have only recently joined this forum and have learned a great deal of important and useful information from fellow members.

Thank you all again.

You would need pretty big HP before the stock airbox won't flow enough - south of 400, until then, the stock airbox and a drop in are just fine and generally will be getting cold air better than dual cones.

He's right on the money, more or less... An intake makes great noises under the hood, and might give you a small bit of hp on the high end, but they really don't do much else unless you are running a 400+ HP engine. Better off with stock or even a drop in filter... Personally I'm getting a K&N drop in filter, after warranty ends (Aftermarket FMIC and Oil Cooler)... If your worried about temps, that's what you should do as well...

as with any forced induction car, the more volume of air you can get into the system, the happier your engine will be. While the temperature coming in from the intake side is important, test results shown give the stett cai a few degree F advantage, which doesnt really translate into much difference vs a DCI if you consider going through the fmic as well etc. Overall, when your engine needs more air, the stock airbox will be limiting you. While you may not need more of that air now, as soon as you strap a tune on your car and are essentially adding 80% more boost, a little more air is beneficial, even at the expense of a couple degrees higher intake temp.

all in all...get FMIC...it makes a huge difference on AIT in comparison to the intake, which you need to increase volume of air brought into the system

sadly its not a simple answer

why not find out for only 100 bux?

the sound is really cool, with a high powered tune it can make a difference but not big from my experience.

If you don't want to spend a ton, go and pick up two dual cones from Autozone or Pep Boy's and make your own. Take off your stock box and put on your two cone intake filters on the intake hoses, clamp and your done. There is a DIY somewhere.

With the amount of coin you've dropped on the car, angst over $200 for a DCI is not making the most sense to me.

Why don't you guys ask Terry what the wastegate duty cycles look like on a tuned car with the stock intake. I think you will quickly find that running a tune on the stock intake is not a good idea.

I've seen a few people on this thread recommend a drop-in filter. Are these really better than the stock OEM filter? If so, which ones are people finding to be actually better (K&N, Helene Streamline, BMC, ITG, aFe, Macht Schnell)?

The funny thing about drop-in filters is that they were dyno tested and showed no gains, but no one seems to believe the dynos. It is kind of odd.

Only good thing about a drop in, is you clean it and re-oil it and drop it back in again, don't have to worry about buying a new filter every 20-30k miles...
