I was wondering if anyone know where I might be able to find some EGR port caps? Not the replacement ones either. I've seen a few on here that are removable with an allen wrench. Thanks in advance.

 

Pictures of what you're talking about?

 

I know that t wouldn't be smart to do it while on the car. I have a new bigger and better manifold going on the car soon. I just want to be able to clean the ports as needed. I've seen ones that have the Allen wrench top to it in different colors, could I find these at a hardware store or an automotive supply store?

 

Here are some anodized Set Screws. I highly doubt that hardware stores will have these. Automotive specialty stores that carry Earls Performance or Russell Performance products would probably have some in stock.
