intake manifold spacer
Hey guys. I was wondering if anyone is running those plastic spacers for their intake manifolds? I know a ton of my friends that did that mod to their cars, it's supposed to keep the engine heat from getting the intake manifold heat soaked.
Here is one for the fd http://www.advancespeedshop.com/gizz...015-p-138.html
Do they make it for all applications? s4 t2 , s5 turbo, non turbo 6 port?
Also , I got a hybrid turbo, the intake housing on the turbo is very close to my intake manifold. I wonder if getting one of these spacers would cause clearance issues

There can be minimal gains on some piston engines but with how hot our engine bays get it's not going to do anything for us. Plus the OEM gaskets are pretty much like this already except slightly thinner.

Our cars come from the factory with that thick layered metal gasket. This one just seems to be made from some different material. If you were building an all out race engine where money is no option, I would say go for it. The gains will likely not be noticeable at all and I wouldn't even bother on a street car.

I have those or ones like those anyways. They don't do anything for heat but they are reusable gaskets that don't need to be siliconed or anything. Just clean off the intake manifold flanges and in they go. Reusable forever. That's why I bought them so I could take apart my manifolds whenever I want and never buy another gasket.
I got mine through ebay. Do a search for rx7 intake manifold gasket look through them and fine the one that claims to be a heat sheild even though it doesn't matter on the rx7 since its too hot. They cost anywhere from 25-35 dollars.
It makes your repairs alot cheaper to not have to buy gaskets because a fule hose is weeping under the intake or the ect needs to be changed or anything else under there.

Yeah if you get the ones cut from plastic they are reusable. The ones in the link look/sound like fiberglass.
Plenum spacers are a slightly different product. It's the same as a crab spacer for older engines. The theory is that by increasing the total volume of the plenum you have more total air to draw from preventing starvation at high rpm. I've only ever seen good results on older engines that have horrifically designed intake manifolds. The gains are normally from the extra space actually easing the angles into the runners.

^ yea that was the big thing for the Z33's. The plenum was nice and wide but it wasn't very tall and the spacer really helped to increase the volume and thus the flow at high rpm /boost. But if this thing is easily re-usable that would definately be worth it with all the times I've taken apart the intake on my n/a.

Very good input. The main reason I was looking at this part is because I get a lot of heat soak when my car is parked for a period of time after it's been sitting after it's been warmed up.
It really looks like heat wrapping my turbo sounds like a better solution. The clearance between my turbo and intake is too clase already with the the bigger intake side anyways. I'm not buying this
