Searching for a hose coupler

Anyone know where I can find a silicone 90* coupler to mate the 4 inch TB to a 3" intercooler hose?

I just grabbed that one ^^. Thank you. I'll let you know how it fits. If it's too tight i'll grab the 4 incher. No big deal. I'm not really in a rush.

I used that same one for my 92mm fast throttle body, the 4" barely fits on it. It needed a 4.25" clamp too.

What throttle body are you using ?

It's a stock TB that I got from POTZ on Ebay. The od of it was just under 4 inches I think.

Just an update. I ended up getting both the 4 inch and 3.75 hoses and you're right, the 4 inch one is definitely too big. I will be trying the 3.75 one tonight.

Here's the thing, I haven't tried tightening it with a clamp. I just put the 4 inch one on and said, Oh ****, feels like my sock on my 4 year old's foot.

I bought both and today the 3.75 showed up so I will report back to say how that fits.

I had those 3.75" to 3.0" couplers made specifically for stock LS throttle bodies. They are a very tight fit and should hold boost without an issue. Also have the 3.75" T bolt clamps.
