Nismo differential cover...does it work?
I'm installing an OS diff this week. While I have the pumpkin out, I was considering the nismo diff cover. It doesnt have space for a bunch of fins and only the bottom 40% is finned. I seriously doubt a lot of air gets back there anyway. I'm using the car exclusively for grip/drift weekend stuff. OS tells me their diffs don't get "as hot" as others because of the way their's "locks".
Is anyone here using it with noticable results?..or are most just assuming it's doing something.

From what I've read the Nismo Diff Cover just dissipates heat away from the diff, kind of like a Heat Sink on a CPU in a computer. Its just supposed to make the heat travel out of the diff. If you look at the claims on the Nismo Diff Cover I believe it states that and also supposed to increase the Diff Oil due to the cooler temps...someone correct me if I am wrong...

i agree as after drift runs ive actually climbed under the car and placed my hands on the oem diff cover to feel the heat.......and the Nismo cover does dissipate the heat and make the diff overall cooler..
As for jacking, I jack from drivers side REAR Toe hook.........done it many times and its quite strong spot for jacking.....my jack lifts the entire rear off the ground enough to do rear wheel changes at drift events.....
so i wouldn't care to jack from the diff......

^ You need to make a drive tool. I made one from a small piece of pipe from Home Depot. It cost me about $3 and 15 mins of grinding with a cut off wheel. I'll post pics up later today. Basically, you cut a channel out of the pipe for the bend/nipple part of the vent to fit into...similar to an O2 sensor removal socket.
You could also try to freeze the vent in your freezer over night. You shouldn't have heated the cover itself. If you used a torch, you may have distorted the vent hole.
