This kit includes the adapters and flanges you need to make a custom charge pipe for your B48 or B58. Manufactured from 6061 aluminum, this kit offers good durability with exceptional weldability. We use these to make our own intercooled charge pipe for our race cars. 

This kit includes everything in the pictures:

• Throttle body adapter flange, for 3" tube
• Turbo outlet flange, factory style, for 2.5" tube
• Charge pressure and temperature sensor bungs with bolt
  
• Does not include wire clip - Use the wire clip off your original factory charge pipe where it meets up to the turbo.
