great write-up pingu. keep us updated on any changes with mpg.

also, did you have any plans on a Neo or S-AFC?

I ended up using the 500 degree high temp spray paint made by dupli-color. I used their hi temp primer also. I am currently looking for 1/2" vacuum hose. It seems like it is almost impossible to find vacuum hose in that size. The stock hose that came with the kit collapsed (it was pretty flimsy).

I was looking for a flat black but there I could not find a hi-temp flat black.

No plans for an aftermarket computer.

I haven't ran a tank of gas with the pipe on yet. I had to take it off because I was painting it and needed to use my car. I average around 25mpg (calculated after putting another gallon into the tank after the pump stops, yes I top off my tank, sue me ). I drive very slow compared to everyone else on the CA freeways. I also have the tanabe hyper exhaust so I wouldn't be able to give an accurate reading if your car has the stock exhaust.

What were your findings for increased mpg's?

Guys,

Where do i find this part (red arrows) ?

Thanks,

So this is definitely a bump, but just did this. It is louder but not by much, didn't really notice any performance difference, but for the price I'm happy with it.

Hey guys,

I tried doing everything I could to make this DIY work for me and I couldn't. I have a 03 gs300 and no matter what angle i cut the intake pipe at, it didn't sit well with the stock box. So I just went back to the OEM setup. It actually has better throttle response with the stock setup. I will agree the stock setup is way heavier but I rather have better gas mileage and no lag in throttle response. I also went to O'Reilly and found 1/2" vacuum hose that I ran straight from the intake arm to the block. Just bought a lot of it and it worked out fine, just wasn't my cup of tea. I followed all the instructions that was given but I think this just works better for the IS300 because of how the stock pipe with the MAF sensor sits lower so you can have more of the pipe going to it. The pictures will show you what I mean.







Notice the pipe is to much at an angle. It defeated the purpose for being straight through. Also the rubber coupler was really bent but you cannot see it from the pictures.

Again, this may work for others and maybe i didn't do something right but I just wanted to show my results and share with you guys.

Still a great right up pingu. Hope it works for you others with a GS300.

I would personally do one of the following:

- Use a silicone elbow off the TB, then a straight section of aluminum pipe.

- Use a silicone hump hose at each end to make up for the angles

Or some combination of this.

Also, I think the pipe should have a heat shield or heat wrap.

That's a good idea, didn't even think about that. Maybe I will tinker with it more to see if I can get it right. Thanks "Angus"
