This ad is for a genuine Ford Throttle Body Air Cleaner Outlet Tube. 
This is for F150, F250, & F350 With 4.9L 300Cubic inches 6 cylinder MAF engine. If you do not have this exact engine in your vehicle, this will not work for you.

Brand new, never installed. I received these in a master case, so there is not manufacturer's packaging.

This is the Ford catalog number for this item;
 F5TE-9R504-FB.

Please make sure to match this number to the one you want to replace in order to make sure it is the one you need. This tube is for specific model and engine size. It will not fit all 6 cylinders.
