Since my engine is sans EGR, I decided to bypass the coolant passage on the throttle body to see if getting cooler air into my engine would make a difference. Oh yeah, it does. A big difference. My truck feels like a rocket on the freeway now. Just another reason to desmog, guys
But, I wouldn't do this if your EGR system is still installed and working. From my understanding, that coolant passage helps cool the hot exhaust gas entering your intake manifold.
