A few months ago I noticed a tear in theintake to throttle body silicone coupler. I promptly when to home depot and bought at 4 inch rubber coupler to get me by.. I ordered a 4 inch black silicone couple online and thething will not fit.... Is 4.5 the correct dia?

I guess I will try 4.5 inches but does anyone know where you can get a replacement online that is decent quality but doesn't cost and arm and a leg.

 

you can try my buddy John at http://www.racepartsolutions.com/categories.asp?cat=26

 

I too have been wanting to replace my silicone hoses that came with my CAI. If you are replacing those, I sent a pm to "taco bill" who gave me the dimensions needed for the two different hoses since I dont have my mustang stored at my house atm. He linked me to here: http://www.hosetechniques.com/produc...oducts_id=2814
and the dimensions he listed for me are these:
Silicone Turbo Hose

4.00" ID (3.00" long)
4.50" ID (3.00" long)

Color: Super Black

Again, this was his response when I told him I needed the two hoses for my K&N CAI for the right sized replacement hoses.

Hope this helps if thats what you were talking about (not sure since I didn't see u mention its for a CAI), but figured I'd mention it just in case.
