Help identifying oil leak

Hey fellow NAMers, I have a decent leak coming from under my intercooler which I'm assuming is from the supercharger. Here's a picture.






If anyone could confirm that and point me towards a proper gasket/seal replacemen that'd be much appreciated.

It's hard to tell from those pics.

My best guess is the inter cooler boots. They are known to age and also collect oil. If it's a serious air/boost leak, you will also have roughness and maybe some codes, so look into it.

The supercharger is pretty far below there and it holds very little oil (a few ounces) so it would be toast if you are seeing oil all over the engine.

I figured it was an intercooler boot. It hasn't been collecting long I know that. Engine isn't rough yet. I do get a slight dry-ish sound when the supercharger starts up.

Something in that area does sound like the intercooler boots as David stated. It would also be a good idea to clean the intercooler once you take it off to replace the boots. Driver side IC boot HERE and passenger side HERE if needed.
