JoeZ Intake
Hey, I am a new Lexus IS350 owner and was looking to add a few mods to my car
I heard JoeZ is one of the best intakes out there for my car, but I have no idea where to find it. I PM'd JoeZ but haven't gotten anything back. 
Anyone know where i can find one new or lightly used?

The filter is the same place it is right now, inside your stock airbox.
That site sells several different drop-in ISx50 air filters if you want to replace the factory one, including ones from Cosworth, HKS, and a stupidly expensive one from TOMs

hahaha so i didnt read the description on that it uses the stock box. how legit is just the pipe though? i've always had just a replacement short ram in my cars. it gave my car a nice lil growl and a whistle at high rpm's. how does just the pipe compare?
op sorry for the highjack

It's not as loud, given that it's just a tube without baffles - it's louder than stock (from what I've heard - I don't personally have one), but not as loud as a short ram. A short ram is loud because the intake element is exposed.
JoeZ is the only intake that I think has a legit dyno associated with it. 5-6rwhp was the gain. Other "companies" will post some claims and whatnot, but I have yet to see an honest dyno from one. Add to the fact that a short ram is going to take ambient engine compartment air, which is leaps and bounds hotter than the air fed through the stock intake through the grill.
The answer is pretty clear, if you're looking for the most power. Honestly, the intake from Lexus is pretty damn efficient - not a lot of room for improvement, but JoeZ did the best job with it as far as I'm concerned. If you're looking for it just to have a sound and don't really care about making more power (or hell, if you're happy with less power) then buy an Injen, ARC, AEM, whatever, and pay anywhere from 2x to 3x as much.
:edit: BTW, check out this dude's thread. He actually measured IAT's for a short ram vs. a traditional intake.

Fitting the IS350 with the K&N Engineering 69 Series Typhoon air intake was a straight-forward operation. The supplied heat shield was installed which according to K&N, "isolates the filter from the engine compartment keeping the air around it cooler." After bolting all the factory accessories and engine covers in place, the IS350 spun the rollers of the DynoJet once again. With the K&N Typhoon air intake installed, a huge increase in power was seen on all points of the dyno graph. The K&N intake's powerband seemed to mimic the factory curve with a 5.9 horsepower increase in peak power. The biggest and most noticeable improvements in power were recorded from 3,000 RPM until 6,000 RPM. In this range, an additional 10-to-18 horsepower were found. Not only did the K&N system bring peak horsepower up to 276.41 whp, it also brought torque up with an additional 9.88 lb-ft; this finalized the torque figure to 248.39 lb-ft.
However....I'd want to tweak the heatshield to ensure a perfect fit to keep out overly hot engine air...
DSport magazine did a dyno Test and Tune and used the K&N intake. They found:

I wonder how many ads K&N buys in that magazine....heh, anyway, 5.9 is pretty comparable to the Joe Z (which is a ton less $)
I don't see an actual dyno graph posted online for the story to judge the "10-18" claim but I'm pretty skeptical of it and wonder if there's not a shift-spike in there or something
How? Was the hood open? Most dynos are run with the hood open, but I can't ever recall anyone driving very far with an open hood unless it is completely removed. If the hood is open, it's a stupid dyno. It doesn't reflect what will happen in service at all.
There are MANY tricks one can use to push dyno numbers up...

Like I said, legit dyno. No fancy wordplay with this 10-18 hp being "found". I want peak and I wanna know where it occurred.
Again, how much is the FIPK or whatever they're calling it these days from K&N?
