Installed the Evosport intake manifold spacer kit yesterday. I wanted to have less heat build up in the engine and reduce air intake temp. My buddy did the work and it was pretty straight forward. The kit came with 2 gaskets and the 2 spacers. I purchased 2 more gaskets and longer bolts.

After removing the manifold we discarded to old gasket and put in the spacers along with the new gaskets. so its basically gasket+spacer+gasket, all of the parts were applied with a layer of sealant so I don't run into and leaks.

Here are some pics.

Cool, why did you add another gasket on top if it wasn't in the evo kit? It'd be nice to log IAT before and after to see.

Its not mandatory but I just wanted to put an extra gasket just to be on the safe side. I would definitely want to log it and see what temps im getting.
I doubt ill see any hp gains but I would imagine it would give out more efficient power becuase of the decreased temps.

Did you only use longer bolts bc of the extra gasket and where did you get them from? How long did the install take I may try this one.

I used longer bolts becuase of the spacers them selves, you could get them at Home Depot. The install took around an hour.

you running a tune or headers?

OE tune, no headers.

Nice project. Interesting to see how much IATs improve. Might get you some timing back if they come down some.

OE should be able to tell you.

How do you get the bottom airbox out? Do you just pull straight up?

I would really want to know the IAT as well. Im sure OE Tuning would help me figure it out.

There are two tabs on the bottom. After you pop those out the rear airbox comes right up.

let us know if you notice a difference

How exactly does this spacer affect IAT?

Am I missing something, cause I can't see a clear link between inlet spacer and heat reduction...

Basically in theory,they are supposed to be a barrier for the heat coming from the engine block so as to not heat soak the intake manifold&increase IAT's

other companys call them thermalnators

Exactly.

The spacers themselves are not made out of metal, they look like they are made of some type of rigid fibers.

Most likely, they're made out of phenolic material.

Your right. I just searched it.

How thick are the spacers? 1/4", 1/2" etc....

They look to be about 1/4" thick, give or take.

Hey , Just wondering if you gained any HP increase.
When I did some research , other manufacturer were saying, reduced in
IAT will gain 3 degree timing resulting in HP gain .

What do you think ?

Also How do you remove the intake manifold? I think my car needs to have the

intake gasket checked.

id becareful with the bolts you used. dis-similar metals tend to not get along, thats why the stockers are magnesium

I thought the OEM Intake bolts were aluminum and yield to torque? I am not sure dissimilar metals would give you a problem for this application as there should not be much moisture to cause any galvanic action. The torque is porbably pretty low but a drop of loctite should keep the bolts from loosening.
