JoeZ intake, is it just a gimmick?
Hey guys. So we all know about that JoeZ's intake is just a pipe, and they claim it gives 5 extra HP.
But if we all think about it, is it even possible that a replacement pipe that ALMOST has the exact same shape and diameter (I beleive it is like 0.25" thicker only!!) would make any difference at all??
I could only find 1 vid on youtube with a dyno, but they dont show the dyno, nor could I beleive it.
Most of the time id imagine its the JoeZ company itself claiming it makes 5hp just for marketing...
But nobody ever proved it makes 5whp, right?
It looks to be a good deal for an easy 5hp, and id definitely buy it if it made any difference at all, but can anyone confirm??
For the record I bought a K&N drop in air filter, and planning to make some holes in my stock airbox, just not sure to get the JoeZ pipe or not...

That is completely not true though. That is honestly what is making everyone beleive it works.
First of all, that video on youtube does not show you the computer screen and show you the dyno results. The guy who made the vid simply said it gives +5hp on the comments...
Second of all, that video could easily be from the makers of JoeZ, or maybe they paid the guy to put it.
Im not saying its fake/rigged for sure, but there is a chance. If I knew for sure it give 5hp I would surely buy it, but there is no solid proof or evidence at all.

JoeZ himself is a member of this forum, and an asset to the Lexus community. The parts he produces are dyno proven and very high quality. He in no ways boosts his dyno numbers just to make his product look better. He even comes out to car meets to mingle and make himself a known member of the community, to show he isnt just out to make money, he enjoys helping everyone make their car a little more aggressive. Saw him at the Pursuit III last fall when i drove to Cali. 
His intake may look similar to a stock intake, but the internal smooth walls of the JoeZ pipe are where they differ from the stock pipe which has ridges inside it. This causes a more laminar flow of air which in turn creates more HP, to be very basic here (and also causes it to give a little more "roar" where the ridges help negate noise, i believe).
Skepticism isnt a bad thing to have, but he does not lie about his products.

From what I last remember when i looked at my stock intake pipe, there was 3 things attached to it. So i assuming with the JoeZ, all of those 3 things are removed?

Except for the part about it being true.

With dyno charts even.
IS 250 White
6speed Manual - 4,401 miles
Base Run
Max Power 173.3 Max Torque 162.5
w/Joe Z Intake Installed
Max Power 179.3 Max Torque 168.1
Gains
Max Power = 6 RWHP* (rear wheel horse power)
Max Torque = 5.6
IS 350 Black
6 Speed Auto - 4,959 miles
THIS IS THE SAME IS350 WE USED IN THE FIRST DYNO TESTING DONE ON 3/9/2006
Base Run
Max Power 265.8 Max Torque 241.7
w/ Joe Z Intake Pipe Installed
Max Power 269.7 Max Torque 245.4
Gains
Max Power = 4 RWHP* (rear wheel horse power)
Max Torque = 3.7
(the * is to mention they used 4th gear, which is what you'd expect em to use, it being 1:1)
The '5 hp' often quoted splits the difference found in the two above dynos.

So when installing the JoeZ pipe, where do those things connected to the stock intake pipe go? Do they just dangle around near the engine? What are they anyway?
From what I last remember when i looked at my stock intake pipe, there was 3 things attached to it. So i assuming with the JoeZ, all of those 3 things are removed?

The square thingie doesn't connect to anything but the intake pipe itself. It is just a sealed box wiht one open end connected to the intake pipe to silence the induction sound.

Do those dyno tests prove that the air filters weren't changed? How do we know an F-Sport drop-in filter was installed along with the intake tube? Or maybe the base run was with a really dirty filter and a new one was installed along with the intake tube?

The Joe Z doesn't replace the filter. At all. It has nothing whatsoever to do with the air filter.
Your question would be like asking "how can we trust the dyno result of these headers? for all we know they changed the spark plugs between tests????"
And FYI it has been on the market, and dynoed, since a couple years before the F-sport intake (or filter) even existed.

Yes it would be like saying how do we know if they didn't perform a tune-up on the car with the run using the performance header. Headers alone would give some gain but doing a full tune-up and going for a run would yield more horsepower gains when the car really needed a tune-up, and it is also considered lying with numbers.

Why are you so skeptical? This intake is made by a fellow CL member and IS dyno proven. All it replaces is your stock intake TUBE and NOT the filter. The dynos performed were with cars having around 5k miles. Even if you add an aftermarket air filter, your gains will be 0-1 hp. It would make no sense to replace your air filter at only 5K miles. Even if they did, that 0-1 hp wouldn't even show up. Just saying

You really need to read my post more carefully. Yes I see those dyno tests average a 5 whp gain. It is ASSUMED they just swapped the Joe-Z tube in, BUT maybe what they DIDN'T tell you was they also put a fresh air filter in the STOCK AIR BOX when they took out the black rubber intake tube in place of the Joe-Z. How do YOU know they didn't do that? Get it now?
