Hey guys,
Well i bought a cool little intake from ebay. Its got two connectors on the new tube where you connect the two larger hoses.
But theres two smaller vaccum lines coming from the back of the stock air box that idk where to put them.
These two lines right here

But what i notced is that the one on the left has a suction that if i take it out of the nipple from the stock air box, it idles higher. And if i plug it, it idles lower.
The other line doesnt make a difference if i disconnect it or not.
The one that has the suction leads to here where i pointed my finger.

Should i cap both of them off? Or do i let it run free but where would i run it to?
The tube only came with two nipples for the larger hoses but not for these.
Sorry for the ugly pics.

hmm never heard of them or seen em but ill probably jus look for some threaded nipples though.
Could i use like silicone or rtv to make sure it seals good? Or little space wont make a difference?
