It runs good and seems to have a little more pickup off the line. Really I didnt notice it running bad before though. I ran the last tank down to empty and just filled it on Tuesday so I havent been able to see if gas mileage is better. Thats exactly what happened to the manifold on my brother’s truck. ---

I have one right now, an 04 with 27k… cracked pass side, no studs rotted. I have seen 06 and 07 with leaks but no cracks. Yeah the tiny hardware is usually the problem first though. ---
