What the name of the connector for the intake hose shop says they need to replace both throttle body and hose. Does anyone know why?
Its the charge air tube (about $120 if bought online). The clip is pretty thick, and not that easy to break.
We had to replace ours as it blow off (over-pressure due to oil in the blow-off valve, thanks to the CAI). Nothing was wrong with the tube, except we lost the rubber o-ring seal inside it (would no longer fit tight on the throttle body (maybe why they want to replace both (easier to throw parts at it instead of a proper diagnosis, especially when its not your $$$.
The tube at the throttle body goes on easy (push down, slide clip on). you will need to change over the sensor (not hard). The bigger challenge is removing the tube at the intercooler. If I recall correctly, i had to remove the wheel well and under body plastic pieces.
