I have read about a lot of praise for the Joe Z intake on the my.is forums. I wanted to ask the question to my fellow bitoger's on whether you think this is worth putting on an is300 and if so what kind of gains I can expect. Oh I have an 03 IS300 and here's the link to the Joe Z thread: http://my.is/forums/f131/joe-z-intakes-stock-your-2001-2005-is300-359217/
Joe z intake question

Looks good for sure. If it's larger and straighter than the stock pipe, I'm sure it flows more air.
My only question is will the is300's computer respond to the added air, or will it make adjustments to run exactly the same as before.
PS-Love the is300!

Hmmm that is the question, lol! I just trust the bitoger's judgement more than I do those on the my.is site. No offense to them 
. I have also been looking into the srt pipes also...In your opinions which do you think would be the most beneficial? Here is the link to the srt pipe http://www.swiftracing.com/SRT/item.aspx?id=2&u=2000003

Your engine control system should have no problem adjusting to that small percentage change in system airflow.
If you get anything close to 7 hp, it's good deal.
Haven't any of the IS people run their own dyno tests on it?
Edit: That's lot of power increase for an intake pipe that still uses the stock air box. I suspect reality is a lot less.

If you want to be honest with yourself, can you find something similar? Take a look at generic warm air intake pipes on Ebay and see if they can be modified to fit yours.
I'd like to see the stock one to compare. If it is convoluted or with a resonator on it, this piece of pipe may very well help a lot.
But a piece of exhaust pipe may do the same.

That second intake is a wee bit over-priced for what you get.
The first one is sort of bunk as well. I mean, you don't need a fancy piece of aluminum with a logo on it to achieve better flow.
Save your money on something proven to work, like a drop-in filter. Or an intake from a reputable company, like AEM or Injen. Those guys actually model flow a wee bit and test-fit to make sure their intakes are of some benefit.

What problems will a piece of metal with a hole in it give you? You want to spend $90 on a piece of metal, or you can find a generic that will fit, spend $40, if you want to upgrade to a cone or for the drop-in, and you still have money in the bank. It's not an alternator. As long as there is a port for whatever goes there, and it fits, I don't even see a bracket.
