Spacers keep the intake and t/b off of warmer parts of the engine…

When the car is heated up the block and anything connected to it get warm… one hot part heats up all the other parts…

A intake spacer raises the intake off of the lower manifold so theres no metal to metal contact helping reduce the amount of heat soak its picking up from the rest of the motor…

so that way when cooler air comes in, it stays cool and doesnt heat up before it even gets into the intake…

something like that im tired so it prolly sounds garbled

yeah that sounds right.

@Ilya"

Did you get to keep the product?

I once ordered some lights on EBay for $50 (bumper lights) and never got them. I disputed via PayPal…and then 3 weeks after my dispute was closed in my favor…the lights came in…haha.

They prevent heat from transferring from your heads to intake manifold and throttle body. Most spacers are port matched to your stock intake ports. A smooth transition from one manifold to another is very important for optimal airflow.

She would have gotten better results had she gotten an IM spacer as well…but a TB one will still cool a little.

On my Maxima…I can see temps drop about 40 degrees with an IM and TB spacer. That equals 8hp and 9tq according to actual dyno sheets.

NWP Engineering makes the Maxima ones.

It’s not because of heat soak…the spacer increases your runner length…creating velocity…which equals more airflow…it also creates a smoother transition from throttle body to intake manifold…straighter run…again equals more power. The air coming in your motor isn’t that hot. Were not talking kelvin here…This isn’t open for discussion either you either understand how a motor works or you don’t. You wan’t to talk about intake temps affected power output? Lets start a new thread…humidity robs you of power not heat…unless it’s temp increases of 100 degrees or more than thats a significant temp change.

Depends on how well calibrated it is…

Can I megasquirt it…please!!!

Tricia def wants a megasquirt.

lol you basically re-phrased me.

It’s a very similar principle as to why your car is more peppy when it’s 32* outside as opposed to 92* outside. You could have 20% humidity both days and I’m pretty sure your car will run much better on the colder day in terms of throttle response, etc. Unless it’s just Maxima’s…which I doubt lol.

Lower temps = better car performance. I’m sure humidity plays a role, but so does overall air temp.

Well thats too bad…JJB’s…for the money there great.

All cars run better when the air is denser....what i'm saying is the t.b. spacer isn't giving you that drastic a drop in temp and that it's the increased runner length increasing your power and throttle response.

Haha, got it. Not up to par with the interwebz lingo I guess. On a side note, usually longer runners will increase torque but not help HP.

You can megasquirt the 240… I’m gonna need some assistance with that one.

a TB spacer wont do anything for heat. a phenolic gasket will. and they are layered between 2 normal gaskets where the manifold meets the head

Also remember were not just talking about the TB Spacer… The TB Spacer heatwise isnt much…

But a Intake Plenum spacer drasticly redueces temps on a car…
