So, I know where this air hose goes.. It comes from the air box, and then connects the all of the 4 TBs together. What purpose does this really serve? Would it be so bad to just plug those up? It seems redundant as the four big tubes on top of the TBs also come from the air box, and is really just another possibility for an air leak. I know there is an oil separator in the air box, but the hose that goes to the back of the 4 TBs doesn't come from the oil separator (as it shouldn't).
