Hi guys.

This is an official intake comparison for all ISF intakes (I know there are some I left out like iCode, and JDM tubes/DI Filters).
I have owned a stock setup, an Injen Intake and now own a takeda setup, and the Takeda is my favorite by far.

Intakes:

K&N - Pro's: NOISE; Cons: Heatsoak, loss in power
Injen - Pro's: NOISE; Cons: Heatsoak, loss in power
Takeda - Pro's: Air flow, Noise; Cons: None to date
Joe-Z - Pro's: Like the stock, except allows for a smoother air flow.
Stock - Stock...not much noise, but no loss, nor gain

When I had the Injen intake, it roared at every RPM. However, it started feeling sluggish after prolonged use of the car. It was subject to heat soak.
The K&N, much like the Injen (inadequate heatshield), is there for show and noise.
Do not succumb to either of these for any dyno's you see on the both.
I have seen a dyno on the K&N and it was reported that a loss of ~15 whp occured.

The cone filters are for show and noise, soley.

However, the Takeda is different. The reason I sold my Injen for the Takeda is because it brought back the ISF Dual-Stage air box. The Takeda intake cone filter is made to fit into the stock box, with an enclosing part of the Takeda heatshield.
With the Takeda intake you get the throaty roar of an Injen, and the smoothness of a stock intake.
The Takeda filter has a bigger velocity stack than the injen, but an overall smaller filter that fits into the stock box. When the dual stage second flap opens at ~4000 rpm, it roars. Granted, it is not as loud as the Injen, but is just a few decibels under it. Power loss seems to be non-existant.

The Joe-Z intake tube is for aesthetics and clearing up air flow. I would label it as the most efficient intake option, when paired with a high flow air filter, such as Tom's or aFe. The Joe-Z simply replaces the stock tube that has a restrictive build (air resonator) (stock tube keeps the noise level down --afterall, it's a luxury car!)


Overall: Cone vs. Drop-in

Do not go with an open cone filter system (like the Injen or K&N). They are subject to power loss, sluggish throttle response, and heat soak. They only add to the noise.

My pick is the Takeda: has the noise, has the power

However, if you do not want the extra ferocious, yet elegant roar of the V8 produced by the Takeda, the Joe-Z Tube with a HF DI filter is the way to go.

I will soon update this thread with the RMI scoops...
They will add to the gain (I had a G35 where I modified the air snorkel which allowed for more air into the engine and felt a gain).



Best ISF Intake: Joe-Z w/High Flow Filter or Takeda aFe Short Ram Intake

Not a bad review Joez

I appreciate your thoughts on this but how in the world is this a complete intake comparison thread. No intake temp loggings, no cfm flow rates, no back to back dyno numbers, no afr numbers, no nothing nada zip.

Sorry but ....no

My homemade intake feels like it gave me a gazillion hp which = the best intake evaaa!

Now does that statement sound complete and accurate? Nope

Also, sorry to burst your bubble, but even with the faulty comparisons we have seen to date the injen outperforms the takeda. Infant the takeda had the greatest loss of power from stock

I am not speaking from numbers or extensive testing, I guess the title of the thread is a bit of a misnomer.
I am speaking from personal experience of driving with 3 different intakes.
Do you have any evidence of the injen intake having higher numbers than the takeda?

there is no point to argue over this comparison as the test was already done by Figs. The best intake is stock period. If you don't believe me then take a look at his intake comparison thread...

There is a loss with any cone filter,
But I felt Takeda to have minimal to no loss.
Stock can't give the best numbers because the joe z clears up the air passage compared to the stock.
Basically, the joe z is a stock intake with a shaved resonator.


The only reason I pick the takeda over it is because of the noise.

There is a thread floating around with the comparison. But yes the injen made more power than the takeda.

I run the injen, love the sound, and love the look. That's enough for me.

stock filter with joe z intake pipe is the best for rwhp, correct? or stock all the way including stock pipe?

Think about it. Stock vs joe z.
Joe z is simply a stock tube with shaved resonator so it allows for better air flow.
The JoeZ is a better flowing version of a stock intake tube.
Better flow = more power, even though you won't notice it, if any.
That's why mods work with mods, intake alone won't let you feel gains.

Lexus's exhaust manifold is highly restricted, with primary cats I believe.
When you free up the exhaust manifold with headers, add an exhaust and then the joe z intake tube, you should feel an increase, but minimal.

Intakes do not make a difference on the isf.

i think the people on the boards that are laying down the best numbers at the strip are running the Takeda

I'm with DCoolBeans on this one. It sounds like this is you picking the loudest intake.
I had poor results with the Takada intake and it quickly heat soaked on me.

Hmmm, after I installed my Takeda, I noticed a slight difference in response (to the good) and I also noticed it pulled harder and stronger at higher MPH's. Now, I havent driven long hours consistently to notice a loss of power due to heat soak on it......
I do LOVE that SOUND Though!!!

here is the thread on the intakes...

Like I said stock is best, any other intake is just for sound and looks.
