i was looking at the injen intake on luxurymods.com and it seems like an alrite price, but i was wondering if anyone had it and if they could tell me about its performance. my friend says that the injen cold air intake is more for low RPM's and not good for high rpms when you ar eon the free way. any help is greatly appreciated

don't get it. It's been proven that the BFI out-performs the injen intake. Search for BFI and you'll find out more about it.

O man another intake question. Ok search for BFI. It is the best proven intake for our cars. At most it will only cost $50 and will outperform the injen. The injen isn't worth the $200 bucks although it does make the engine bay look nice! Also search for JspecSC3's custom intake he made, it is SWEET! Nevermind here is the link https://www.clublexus.com/forums/sho...ghlight=intake .

Dont go aftermarket man,just like everyone else said go BFI.(I did haha!!)

Anyone that tells you an intake (ALONE) has this type of effect on your car obviously has ZERO knowledge of automobiles. My advise is to run as far away from the person who told you that and never speak with them again!

i would like to see dyno proven results that a bfi out performs the injen any one that knows anything about cars would never make this statement unless having dyno sheets to back it up.
had bfi on my dads sc400 then went to the injen.. imo much better worth the extra money .. you decide i guess it depends on what your going for. im not going to argue that cost effective comparative to hp gains the bfi is going to win obviously but saying the bfi makes more power

Start here and read why you need a resonator chamber and what volumetric effeciency is:
(Also, go through all the links. You'll find the dyno info you're looking for)

Then go here to see how aftermarket filters flow no better than OEM:

it is proven that aftermarket filter do flow better than oem and i know what volumetric efficiency is.
the factory tubing creates turbulance in the airflow due to the design and aftermarket straight tubing is the most effective flow creating no disturbance. end of story. i also see no actual dyno results on peters page. i will gaurentee you that you will see greater improvement on a dyno with the injen intake over a bfi

I don't believe you. Where are your getting YOUR facts?
But if it's true, i'd be extremely happy and immediately purchase one.

deal i will take my dads car to the dyno and put the stock intake back on with the bfi then dyno with the injen and post results

I've never seen this info. Please post your sources.

This is a part of the reason why a resonator chamber is used.

I'll give you this one. I hadn't been to this section of planetsoarer in about 2 years and it appears that links to dyno and other tests are now dead. But there was a link to dyno results of OEM filter vs K&N vs Apexi vs others. OEM (used in BFI setup) prevailed.

you guys want a box of tissues?

stop crying over 3 horsepower intake.

BFI is claimed to give around 15.
Soarer is stating injen will produce more.

So, STHFU & GTFO.

15HP my butt. Me and Scott (kisoarer) proved that an open intake system yeilds 5hp over stock. Thats the best bang for the buck ever. Free. Quit trying to mod a 170 rwhp motor with $2-300 dollar intake systems for 3hp. With all the money you spend in performance mods for a 2jzge you'll still run high 15s in the 1/4mi and get beat by Civics. Save ur $$ and get a turbo

Open intake is supposed to decrease HP on our engines...
I remember reading it on planet soarer.

edit: and we are talking UZ here , not JZ.
