I've tried researching this topic, but have found little confirmation on what would be ok to do. I understand the Aramid gasket will keep heat out, but how much of a gain is it? And it's it's not significant can I just install the OEM gasket? Getting ready to install the MREV2 and I bought the oem gasket from a local infiniti dealership, but I would like unbiased facts on whats the way to go. Thanks,

 

The Aramid gasket does a great job of keeping the whole plenum assembly cooler than stock. Before I installed mine, I couldn't put my hand on the upper plenum, it was way too hot. With the AG I can actually hold my hand on it, even in our brutal summers here in Texas when the motor's fully warmed up. Not sure what you mean by gains and I can't verify exact temp difference, but I can physically tell it works well.

 

The Aramid gasket goes between the lower plenum and the engine block, there is no OEM gasket there. I'm guessing the OEM gasket you bought goes between the upper and lower plenums.

Like Blue Dream already said, it works great, you should get it. It's as good as a urethane gasket that you put between the intake manifold and the engine block for Hondas and other inline fours - it may not do much by itself, but is a great supporting mod to make your other bolt-ons work better. It helps keep intake temps cooler, which advances timing and much more. By itself, you will not see any noticeable horsepower gains on the dyno, but you can see it working when you look at AFR, timing, and more. It's definitely a great addition with the MREV2.

 

You've got your answer SKYY-35. Aramid is the way to go, anything that repels heat is a very good thing....Gary

 

ACTUALLY there is an oem gasket that goes ther Spoke w motordyne. They push their aramid, but it's fine to use the stock one. The loss/gain isn't significant. I installed the lower MREV2 w/ the original gasket, then the 5/16's spacer and wow what a difference. Lower rpm's and more significant power. Should've bought this a while ago lol.

 

where in the BAY are you?

 

Should have installed the aramid

 

I think there will be gains from the Aramid gasket. It is a significant difference in heat, and it will essentially acts as a cold air intake as the air will suffer less heat soak before entering the combustion chambers. Also, If you work on your car, it is amazing to be able to put your hand on the plenum and not scorch it immediately if you need to fix something quick in the engine.

I would buy it, wait for it, and install it all at once. I plan on buying a thermal gasket for the lower runners as well to reduce the heat even further.

 

This gasket comes with the iso-thermal kit??

 

It is, they also sell it seperatly.

 

Quoted for truth, Tony's gasket goes between the lower plenum & intake. Smh

 

The Aramid gasket is ok - but its not a game changer

you get way more benefit from bypassing the coolant at the throttle body vs the aramid gasket

 

Aramid gasket btw throttlebody and top plenum, engine block and lower plenum as well as coolant bypass. Can't tell any difference in performance but anything that reduces heat is saving power.

 

These guys have a bunch of options for thermal spacers as well, http://www.nwpengineering.com/index.html

They've got some more options on the way as well but I'll be using some of their stuff in the upcoming build.
