Intake hoses.com does have a 90 degree 4.25" to 4" ID Silicone Reducing Elbow(R90B-400-425SR). I have found larger 90* elbows but they start at 4.5", no 4.25".

No, you need 4". 4" will slip right over a 102 throttle body. Not to say you cant squeeze a 4.25" coupler down with a clamp but the 4" coupler is perfect

This is my 102mm setup using a 4" coupler
