Default gasket question

I'm in the middle of removing my plenum. My question is: If one of the gaskets for the plenum is intact and the other tore. Would you replace both with new ones or just the torn one?
I heard the originals are the best but I'm unsure.

Cut your own out of rubber and you'll never have to replace them again.
I did this in the late 90s after experimenting with several other materials.
Same rubber gaskets ever since.
Oh and I'll add it very easy to do with the plenum as a guide.

I did consider doing it that way, but I was a bit lazy. I was already ordering new wires from Jerry so I got the gaskets too.

What rubber did you use? Probably would insulate also.

I used regular black rubber (this is very similar)

You can cut up to 4 out of it for $25

But I'm thinking your right about insulation properties so I wonder if this
wouldn't be ever better. It's 1/4in thick.
http://www.grainger.com/Grainger/Rub...WV6?Pid=search
someone would have to try it. It's more cash at $62 but you can get four out of it. It's higher strength and temp range that what I used so i bet it'd be fine.

In any event that site has many alternatives. You can use there application selector on the side.
Obviously the advantage being you can use them over and over.

I'd use the silicone material since we use a little neoprene at work here and it dries out bad when exposed to UV and ozone or something in the air.

After >10yrs mine seems fine. Flexible and no leaks.
Not much UV under the hood

Jerry's work well, but since they don't have the rubber rings molded into them, I have found that you should permatex/ aviation form-a-gasket the water and oil breather holes to prevent seepage after install.

Of course Jerry's are a must if you port since they are perfectly cut to accommodate 36mm porting.
