I was seeing if anyone has the dimensions for the intake ebow.

I have used ChatGPT to get the measurements of the airbox outlet and throttle body size.
Throttle Body Side:
Outer Diameter (OD): ~80mm (3.15")
Inner Diameter (ID): ~76mm (3")

MAF Housing / Airbox Side:
Outer Diameter (OD): ~89mm (3.5")
Inner Diameter (ID): ~85mm (3.35")

Angle of the tube:
~75-80

*This is taken on the assumption of the diameters above*

In addition, I am trying to make a carbon elbow for the car (Buying a pre-made carbon tube). Could anyone confirm that I need to use the inner diameter of the measurements above? I will be using one silicone cuppler and a reducer cuppler. In my head, I will place the reducer at the throttle body since it will compress the air right in the throttle body (similar to a velocity stack). If anyone has more ideas or thoughts to add to this, let me know.

This project is just about maximizing sound without going to a whole intake system besides the Dinan Ram mod.

Inside Diamter for the MAF - 74.9mm
Outside Diameter of US Airbox with the lip for the air intake boot - 81.7mm
OD US airbox without lip - 81.5mm
approx inside diameter of silicone intake boot - 87.5mm

as per photos with a caliper

I want to ensure that with the elbow, it would be better to get closer to the 87.5mm compared to the 74.9 mm. In addition, I haven't seen a tube that matches my requirements, so I may have to do a custom one. I will try to get the angles and lengths for the elbow later in the week.

[chilledn52]

just make sure at the point of the MAF is 74.9mm for it to make proper calculations.
Unless you get a custom MAF tune to calculate to the new maf diameter,
didnt have any other measurements

[tylerhart_21]

That sounds good. I will make sure I keep this updated on the route I take. I have the idea now; it's just adding the parts to make it work.

I did a quick measurement and from the v brand clamp to the curve is around 6 inches.

I am thinking about using the throttle body part of the original elbow and then adding a silicone hose to the area towards the maf sensor.

The other idea is taking a model of the elbow but using a silicone hose to the front so the flexing doesn’t affect the carbon. The problem is I am not an expert and it’s too much time I don’t have to do.
