Just want to see if the JoeZ tube increases or decreases gas mileage? Maybe stays the same?
I know most of you guys would floor it more after installing the JoeZ tube to hear the difference in the sound it produces.

I really tried very hard to prove/disprove the positive effects of acetone in standard gasoline at the recommended (very tiny) amounts. At first it appeared I had found a significant improvement, but by the time I collected my data from 10 tanks of gas, the results were inconclusive at best. I suspect you'd see the same thing with ANY available aftermarket intake on an ISx50.
While there is no denying it is possible to improve economy by reducing pumping losses on any engine, the losses with the OEM intake are very small compared to anything the aftermarket has provided, hence the comments about not being able to feel a difference or see a difference at the pump. If the intake were a crappy design, the result would likely be quite different, but it isn't a crappy design, so there's a tiny bit of room for improvement. Really tiny.

You're not going to pay for it with gas mileage improvements anytime soon, if at all. The decision is more about do you want to have a coolio shiny metal tube under the hood, or will your ego let you run the stock piece and save the $119 for driving school where you'll learn a lot more about driving fast than you'll ever get from an ISx50 modification?

Not only because of the posts I read here,I don't want the engine to be louder.A K&N and JoeZ will do just that.
The alleged 6HP gain of the JoeZ peaked my interest.Probably wouldn't feel it anyway.

I also agree that gas mileage is a driving habit and as long you drive the same way as you did with your OEM setup, you should technically achieve similar MPG's..
If you drive with a heavy foot after installing a performance modification, you can expect it to drop. Now if your aftermarket modification is poorly designed, it will negatively affect it as well…
Also, as a factual side note:
I never created this intake as a gas saving modification.
As I said many times, I would NOT make this pipe if there was NO benefit from installing it.
The intake makes power, independent Dyno testing concluded this.
6rwhp on an IS250rwd and 4rwhp on an IS350..
A few CL Members have reported the same or better dyno #'s with my intake.
Although it's only a subtle upgrade, it has been proven that it does its job over the OEM tube..
It in fact performs as advertised.. nothing more & nothing less..
Thank You
Joe Z
