I figured that you guys would be the most knowledgably on something like this, so...

I recently installed a ram air hood on my car. I love the hood, but the air box assembly cries ******* in its current state. The piece of rubber that ram air hood (.com) recommends is fine for speed density applications, but it looks extremely restrictive when you try to jam a 4” long MAF sensor between the air box and the throttle body.

In other words, I want a piece of rubber that will fit on the throttle body (oval) then go down to a 3-3.5" round hole in about 2-3 inches.

Thanks in advance

 

Why rubber? You could easily make that out of any other types of material or even buy something that would fit that application in aluminum tubing or something.

 

I said rubber because it would be the most flexable. I'm not sure what the exact length has to be and rubber can be stretched/compacted to cover my margins of error. Where would I be able to buy something like that in aluminum?

I don't really care what it is as long as it works.

 

I went to a hardware store and got some rubber pieces from the plumbing aisle. It works great. No issues whatsoever once you get the piece on the throttle body and the maf sensor.

 

IIRC, the throttlebody connection works with a 4" ID rubber hose. To neck it down, I ended up welding an aluminum reducer.

 

I bought a black silicone reducer on ebay 4" to 3". It was only 3" long. It was $12. I used it to connect an aluminum intake pipe to the throttlebody. After I slid the reducer over the TB and the aluminum pipe, the total distance between the pipe and TB was like 1".

 

Thanks all for the replies. I will look where you sugested, starting with the hardware store since it is the closest.
