Overall, What's the best intake for the car? I was wondering what would get the best mileage for the car performance wise.

TRD or Injen? or is there something better?

[seppuku27]

I like my Fujita CAI with the TRD CAI bumper grill.

[oemking9]

so you can just purchase a different intake and purchase the CAI bumper grill separately?

[seppuku27]

Yes you can go to Toyota and ask for the TRD cold air grill.

[oemking9]

cool thanks.

[armondo]

This information is very useful, thanks! I just joined, and had a smiliar question abou tthe CAI, as I'd like to have one installed. Speaking of installing, would it be best to have Toyota do it, and spend an arm and a leg, or just follow the instructions and do it myself or a savvy friend do it ?

[seppuku27]

Do it yourself just dont take the bumper off like the instructions say. Take off the bottom wheel liner and slip your hand up there to put the filter on. And be careful with the MAF its expensive.

Sorry, but what does MAF stand for ?

Mass Air Flow (the wire thing that bolts into the intake piping)-> it measures the airflow to the engine and adjusts fuel mixture accordingly.

very helpful info guys, thanks...
how is a "blow off valve" better? more expensive too? the more info I get, the more questions I have

[TartanJack]

A "blow off valve," from what I have picked up from power/blower fanatic friends is used for pressure release in high pressure systems, like a supercharger or turbo. A cold air intake or ram air intake (two TOTALLY different concepts), generally, doesn't have the pressure to necessitate a blow-off valve.

I don't recall a blow off valve as an alternative to a MAF. They do different things.

(This post is stated with the author's own note of self-ignorance of power making details and whose xB and alternate vehicle (a MX-5 Miata) are both normally aspirated. My understanding is based on conversations with friends. I may have completely misunderstood what a blow off valve is and be completely wrong. I am fairly confident in my understanding, otherwise I would NOT post. However, I am fully open to correction without argument.)

Your correct. N/A you will not have enough pressure going into the engine to need a BOV.

i know a couple ppl that have weapon-r secret weapon intakes and they love them. weapon-r has that tube that you can route into your bumper to help push air INTO the secret weapon intake. seems like a neat idea.

I am talking about sound. what a concept, SOUND

SOUND

I am talking about SOUND

Blow-off valves makes the sweeeeeeeetest SOUND

I didn't tell him to buy a blow-off valve i said buy a fujita

now improve reading comprehension 1st before posting

thank you, and have a nice day.

4 post and already a duche bag.

Armondo didn't know what a BOV was and TartanJack just answered his question. So calm down.

[ketchup_xb]

best intake is the stock one..with a k&n drop in filter. gas is too expensive still..

[TartanJack]

So . . .
He asked I answered. That was an question in a thread that came off another post previously (and was asked in a way that WAS related). The MAF sensor IS part of an intake system, indeed a vital part and one that can be easily damaged if handled badly. The other post was asking what a BOV was and if it could be an alternative to a MAF. As they do something totally different, the answer would be "no."
In intakes, the MAF (for fuel injected cars if the last 20-25 years) has been a major issue. In the old-style with flapper boxes (like 1.6 NA Miatas), the box is a major issue in intakes and means that most/many do nothing other than make neat sound. Some even are WORSE flow than stock. Fortunately, the xB2 has a "hot wire" (one common term among others) AFM (Air Flow Meter-> an alternative name for a MAF "Mass Air Flow sensor, 2 names for the EXACT same thing) that has insignificant inherent restriction, so much more effective intake systems can me made. MAF/AFMs commonly come up in intake discussions, at least on the car forums I have been part of for the last decade.


Back on topic . . .

Each intake has pros and cons and the "best" is the one that meets your needs with the pros and has as few problematic cons for you and your application as possible.

Perhaps a good way of asking . . .
What are the intake options presently available and what are the pros and cons of each?

TRD intake:
Pros:
-NO warranty issues! (a major factor for many people)
-Trouble free use
-Solid/high quality construction (won't fall apart or have major "leak" issues

Cons:
-Expensive (relative to some kits out there)
-Not huge power gain (limited on purpose, so not close to engine/computer damage issues-> so CAN be OKed by Toyota to not adversely affect warranty)

Pros and Cons of others?


Aside:
Warranties and engine/drivetrain alterations can be serious matters. Many manufacturers allow NO alterations of they will try and void your warranty. In fact, that is one of the issues in Miatas (I know that field, as have had one and "played" with it for over a decade) . . . Most/many owners wait until the warranty expires BEFORE they alter anything at all.
I know of someone (NOT a Miata or xB owner) who had issues with one part of their drivetrain (well after they had altered something elsewhere on the drivetrain) and the dealer said that the warranty was voided because of intent to alter the vehicle performance characteristics, showing evidence of racing or excessively hard driving (both of which are often listed in warranties as causes for them to be voided).
One of the things that impresses me with Toyota and the Scions is that Toyota PROVIDES decently performance enhancing parts at a reasonable price which DON'T affect warranty to void it! That is to be commended.

thanks great info!

I get the same gas mileage as I did before I got the intake. I just don't go pass 3k unless I am passing.

TartanJack you forgot one thing, the TRD CAI is the only CARB approved intake out there right now. The other might have smog problems later on down the road.

Also Toyota has to prove that the aftermarket intake was the cause of the problem.

[oemking9]

so you're gas mileage really didnt improve? hmm i've been hearing different things lol....i'm tryin to find a way to increase gas mileage its friggin expensive right now!!!

[robertjcurrie]

I just got my TRD intake installed...... So far same milage, and the sound in good to.... Totally satisfied.......
