Plenum gasket replacements

[zoomzoom]

I have to replace my plenum gasket on an RB25DET, and it looks like I can get either a genuine Nissan gasket, which I believe is flexible rubber, or a Cometic gasket which I think is a more rigid piece, though it's hard to find info. Cometic doesn't list the info. Looks like the original gasket deformed laterally, basically the seals around the runners got sucked in under vacuum. Not surprising since the factory gasket is just rubber. Does anyone have a recommendation, or info mainly on the Cometic gasket?

I have "heard " for that particular gasket, Cometic is good, but not used it myself. Never had an issue with oem, although mine are pretty new.

Im using the cometic one. Is very rigid indeed. No issues with it.

sure oem is fine, although I can guarantee you will be happy with the cometic. hi quality good aftermarket option not to pricey.

Alright, I've got a cometic one on the way. Are the plastic inserts on the plenum reusable? If the cometic gasket is made from a stiffer material, I'm guessing the plastic will crush down more than the gasket.
