Instead of drilling a hole like the instructions say so here... cant you just directly connect it to the breather plug on an intake?? and also, if nitrous is more compressed in higher temperatures, then isnt having a CAI disadvantagous (if thats a word)?

 

Some nitrous kits need a certin length between the t/b and the nozzle. Usually with a wet shot its closer so the fuel doesn't puddle. Dry kits are farther away to evenly distrubute the nitrous in the air so each runner on the intake manifold gets an equal shot.

 

if its the dry kit, that will be wayyy too close to the intake manifold, it needs to be anywhere from 12-18 inches away (depends on kit)

good luck!,
