yes thats the safari snorkel from ARB, but its for a tacoma, not a 4runner. they do not make anything for our 4runners other than lockers, all my ARB stuff(other than my locker) is for a tacoma, i just made it fit.
i am running the stock alt for now, when i burns out i will probably put in a GM cs144 at like 240amps.
you cant go wrong with PIAA, they have the most simple wire harness and its all plug and play, a 3rd grader could install it
