Intake dilemma
 

So I am looking to replace the stock intake on my BRZ and I have been researching/looking through forums about the intakes out there currently. But I cannot seemed to get a clear answer on which intake is the best.
First dilemma is deciding whether to get a CAI or short ram. I have read CAI is better but also short ram could be better with a heat shield or some sort of housing (forgot what it was called :iono:). But it seems only Perrin has made a true CAI and other brands are short ram.
Which brings me to my second dilemma and the reason for writing this. Which intake offers the best result? I know intake itself does not result in great power gains but out of the little gain it does produce, which one yields the best. From what I have seen/read so far, it seems Injen has the best results but then it seems AEM and Takeda also do too. I am not limiting myself on these so if you provide a better intake with proven results (i.e. dynos) it will be considered. :thumbup:
Finally, to add some notes. I care more about gains than looks. Also, I am not planning to get my ECU tuned until I get an intake AND an exhaust. So even if I decide on an intake now, I will be driving with the stock ECU for a while.

Thanks for reading this long post :party0030:

Get a drop-in filter, cheaper and same/better gains. If you really want a CAI, GrimmSpeed is wrapping up R&D on a promising prototype.

thanks for the quick reply.
I forgot to mention, I recently bought the K&N air filter and am planning to put it in this weekend :thumbup:

I saw the thread about the GrimmSpeed intake. But they haven't given a timeline of when it will be produced. I guess I could wait a while...but I am looking to get something soon.

I see that you have a Perrin intake hose. So you have left the stock intake filter? Did you feel any difference?

I bought the AEM fairly cheap. Ran it for a few months switched to stock for warranty maintenance and never went back. I like stock w/ Perrin drop in the best so far. If you plan on going w/ a tune then buy an intake but i'd only go w/ AEM, aFe, GrimmSpeed, or Perrin.

Ignore all dynos on intakes because they're all top end and have little to negative gains down low (DD rev range).

A lot of us here are regretting out intake purchases, and going back to OEM. That and OFT only supports OEM (for a reason.)

Good plan!

I agree with @tbertran ...... keep it simple, just drop in the filter ..... the stock airbox is just fine ... :)


humfrz

does changing the intake hose require a tune?

The hose after the air box, no.

Look at my post in a thread called best cold air intake. There's everything u need to know about intakes for these cars. (Didn't mean to sound cocky or like I'm a know-it-all cuz I'm not and still hav a lot to learn, but I do know quite a bit on this specific subject. I also made the same post in other threads asking the same question.)

GOOD LUCK WITH WHATEVER U CHOSE :)


For me, there is no glide in pulse and glide :p

thanks for the input. I found your post on that thread and it sounds like the best top 3 choices are Takeda, Injen, and Grimmspeed.

idk about Takeda but I've seen some thread where people were having issues with Injen. and Grimmspeed...still waiting on a production model to be tested lol

so I guess in the meantime I'll do some more research on Takeda and Injen.

*edit*
it looks like the stock airbox with a drop in filter is enough. but changing the intake tube helps a bit. so now which intake tube to go with...or are they all somewhat similar?

All somewhat similar. Drop in filter or complete intake system is my suggestion. Takeda and injen have received some complaints because if a cel issue but that happens with all products and I think they resolved that issue. No need to worry


For me, there is no glide in pulse and glide :p

To be honest with you the stock intake design is hard to improve on. In terms of results and best option any drop in filter and something that smooths out the intake design such as perrin or Supertek is going to be the best for non tuned purposes. Your not going to notice gains but response and sound improves. Almost all of the CAI so far have some draw back without a proper tune...

so you're saying an intake with a tune is going to yield better gains than drop in filter + intake hose?

Of course


For me, there is no glide in pulse and glide :p

The intake tube is only part. The air intake replaces everything and when u add a tune to the mix ur looking at at least double the power of an intake hose and drop in filter.
