Cold Air Intake worth it?
 
I am looking to improve my intake. Any suggestions for the best benefit of a naturally aspirated intake on my 2014 FR-S?

After my warranty is expired I'll update to a turbo or SC.

Thanks for your help.

i can say this much, the "appearance" factor under the hood will definitely be improved.

as for the actual performance gains, ive been struggling with trying to figure out the value of the cost vs gains to me. i cant decide if dropping $200+ on an intake for a bit of sound and under-the-hood aesthetics plus a couple hp gain is worth it. i never show off what's under the hood since engine is bone stock...

If your planning to go FI save your money for the intake just buy any drop in filter, its proven and it works

Some really, really good info, comparisons and cost analysis in the engine tech threads here.
Short version of the story is though that, dollar for dollar, the real value for these cars is in a straight drop in high flow.
There are of course, those that will argue that statement (some will argue anything) but the threads really do show that the stock intake is actually very effective and a drop in can improve it even more.
Now if you want to bling up your engine compartment or are thinking of FI then there may be better choices.
I for one, am very happy with the improvement that I got out of my simple TRD (sorry Shutter) drop in filter.

Stock works great. If it didn't Toyabaru would have changed it. And some of the supercharger kits wouldn't use it either but a few do. This isn't 1990.

From everything I have read, no.

You have to be careful with statements like that...if this were true, our header would have been designed differently from the factory, helping to decrease the torque dip. Not everything is optimized from the factory.

I don't have a CAI, nor will I buy one. Seems that a header and tune are 'worth it'.

Grimmspeed's new offering is mighty enticing. They're touting up to 17WHP gains paired with OFT vs bone stock. We'll see how that goes- I just installed the intake myself on my bone stock last night, and will report back when my tablet arrives Saturday.

At the pricepoint, though, I wouldn't have spent the money if I didn't get in on the group buy.

P.S. have a perrin air filter for sale- used for literally 200 miles ;)

17hp gain off an intake for a 4banger is LOL

and even peak hp gains are meaningless without knowing the hp gain across the entire powerband range. just cuz something makes X-hp at 5300rpm doesnt mean you drive at a steady 5300rpm hahaha

The Grimspeed design certainly is thoughtful, but a note about the reported gains. Most of the HP increase is likely from the tune. Notice that most intake comparisons are made:

stock vs. Intake + tune (the gains from the intake and the tune aren't isolated)

instead of
stock vs. stock + tune vs. stock + tune + intake.

Best money definitely a tune + high flow drop-in filter (any brand). The stock intake already is "cold air". Get an OFT and run e85 for free. Definitely worth it.

Take it up with Chase and his team- I'm not saying I believe them. I'm telling you what their findings were and what they tout. You can see their development and dynos on their intake thread.

From what they are saying, it is the other way around. I find it hard to believe, but their report and dyno sheets claim 10whp gain from bone stock to just the intake, and an additional 7whp was found by Shiv when he tuned the prototype FRS. Again, not saying I believe them, but I am forwarding what they're touting

Guys I'm no spring chicken when it comes to autos- been wrenching since I could hold one and know enough to be wary of such claims. I've followed the development of the G/S intake since they started it, though, and knew it was a great piece for the money (group buy rate, at least ;) )

Plus, I sold the stock airbox and inlet for $100. So what's really $200, when people are spending upwards of 1k+ on catbacks. To each their own

17 is still pretty high for a tune + intake on this platform when the OEM intake has proven to be so effective. Now I want to track down a OFT stg 1 tune dyno (w/o intake) to refresh the comparison.

The problem is that they would have to be all done on the same car, in same atmospheric conditions, on the same dyno.. would really be interested to see!

To address the OP's question (finally, sheesh)... it probably isn't worth it as much as driver mods (a few track days) if you're looking for performance gain. It is considered worth it to some. Most, myself included, would suggest a drop-in filter and call it a day.
