Size of Air Intake On Throttle Body - 155 N/A
Would somebody be able to measure the outer diameter on the air intake side on the throttle body of a 155 N/A engine for me? I'm just wondering if it's 3" or 4" and since my ride is in storage I have no way of finding out. I need to find out so I can purchase the right size silicone coupling for it.

I can tell you without looking it's 3" Thats why everybody wants to make it into a 4"
I can't look at mine either it's all wrapped up

it's less than 3"
2 3/4 silicone hose/coupler will work well

Just to give you an idea...the silicone sleeves that i bought to make my external I/C plumbing are 2.5 inch and they do fit on that....so it is definitely not 3 inch and more....most probably 2.5 to 2.75 inch like Shibby said.

it's like 2 5/8 or something... so u can go up or down from that and the clamp does the rest, lol
