New LS1 Owners - Newbie Tech - slp cold air kit and jaam ram air together??

So my car already has the slp kit but I had very good experience with the jaam kit so could I use both of them? I kno the slp kit is supposed to have the box sealed but would it hurt if I sealed the box to the hood and left the slp kit on?

I would think it could cause turbulence having air converge from 2 sources. How it would affect performance is anyone's guess.

Both together offers no benefit. The intake will suck in from where ever is the most free flowing. By having multiple openings you are essentially causing a leak in your airbox and it will be less efficient than one or the other. I would go with the jaam since it is a sealed to hood which is actually making use of the nostrils.
