Also, I don't remember reading anywhere that the Stillens gave a loss in HP. The only time I remember seeing anything about an aftermarket product giving a loss in HP is the Fujita system...and that was only from the technosquare ecu flash thread...

I Agree with this, Read the same thing..
Perosnally stillens have worked Fine With Me!?

As far as we know, the only intake to give a loss is the fujita...so maybe you should reconsider keeping your Stillen intakes...I'm sure they don't give you a loss in HP

regardless of the heat shields, they're all only going to do so much considering the throttle bodies have coolant running through them, they're only going to cool off so much and it's going to be minimal, but one difference is allowing for a more fluid flow and more proper inlet velocities which is what the venturis will do.

Interesting (about the TB having coolant running through them).
On my last car, a popular free mod to do was the Throttle body coolant bypass. Basically it was two plugs and a tube to bypass the TB. It keeps the TB from getting really hot which lowers intake air temperature, and makes more power.
It's probably only good for a few horsies..... but it's "free."
Anyone done something like this on a G35? Living in FL, I wouldn't have to worry about freezing temperatures.

here's a 3rd party dyno on a coupe comparing the stock vs. JWT. runs were done before intake swap to obtain consistency, then the swap and retest. Says he's getting a mileage increase of 1 to 2 mpg as well.

Well How about these!???
Will these fit the Sedan!? It says their for the 350z HR?
Pretty sweet Ones too!!

From having talked to many shops and distributors i have learned that though the engines are the same, some of the 350Z bolts on will not work on the G stritcly because of the room in the engine bay, with different angles and such, but you can always try if you want...

I like the idea of bypassing but don't want to be the guinea pig.
1) IAT sensor (intake air temp) should only read a lower temperature if the air IS a lower temperature. That would be a good thing.
2) I live in Florida. Frozen TB wouldn't happen.
As far as I know, I don't think there are temp sensors that measure your TB temperature. I wouldn't see the point.
And yeah, I wouldn't want to be the guinea pig. But, I'm not worried about an extra few HP. For the guys with intakes and exhaust, it might be a worthwhile mod.
The only reason the coolant runs through the TB is to keep it from getting frozen and stuck in below freezing temperatures.

i've heard on the s2000 hondas, they've shown a 5hp loss from heat once the car's warmed up... after bypassing the TB, that 5hp came back, so in essence, it's a 5hp gain on a warm motor... we have two TB so I wonder how it'd help there.
