I have a BBk 58mm Throttlebody and I had 2 pretty much stretch the factory rubber hose that connects to the throttlebody and the mass airflow sensor and its kinda restricting my airflow. Does anyone know where I can get a aluminum airtube or something like that to replace my factory hose? I looked through the JEGS and SUMMIT catalogs but didnt see anything. Thanks for your help

 

What makes you say the factory hose is restricting your airflow?

 

Because I had to physically stretch the hose around the mouth of the throttle body and when you look up into it there isnt a straight path for the air to flow into it like there would be with an aftermarket tube type inlet. I have an Ramair hood and airbox an my T/A and the rubber tube is kinda pushed together like a accordian to about 3 inches I guess I should post some pics of what I am talking about.

 

If thats what you are basing your air restriction on, you don't need to worry. To be perfectly honest with you, the stock 48mm throttle body and that factory hose with all those wrinkles will outflow the TPI setup itself, even if you have heavily ported aftermarket parts.

You don't need anything bigger than a 48mm until you are running very deep into the 12 second bracket.
