When I took off the plenum (sp?) and looked under there it definatly is a little redundant about how all the coolant lines are routed in there. From the FAQ writeup on the bypass it does seem perty helpful, and if you do spring a leak, there is only one hose to worry about besides the 6 or 7 under there.... Overall I'm looking for you openions, if you had the engine out would you go ahead and do the bypass as well?
