    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.
