    GM OEM intake tube - help identify a part, please!

    Hey,

    Was about to install a Lingenfelter CAI intake tube on my new Lingenfelter kit, but was stopped by the fact that the tube doesn't have a port that will allow me to plug in the following rubber hose.

    Can you help me identify the function of this piece of equipment, and determine whether or not I can leave it off (perhaps strap it elsewhere)?

    It is part of the positive crankcase ventilation (aka PCV) system. The intake tubes without it are for an LS6. You can drill a hole in the new intake tube an insert a fitting for the hose. (I used a threaded air hose fitting, when I adapted an LS2 throttle body to my LS6 setup.)
