Hi John, glad your back. Although I havent drove the car, or even started it with the FLP's yet (stupid timing chain/damper

) This is what I know about the FLPS.
I took them to a shop to have them welded (the air fittings) but the guy had two plugs that fit right in them (I have no idea what size they are).
I got a set of fel-pros for the gaskets.
As far as the EGR tube on the pass side, I figured I would just cut the fitting off the flex tube that connects to the header, and bolt it up with a nickel or something blocking the hole. I havent started the car yet, but that should stop any leak.
Coming from MACs, the plug access is pretty bad
