Throttle Body Trumpets
thingiverse
Custom designed Independent Throttle Body ("ITB") Trumpets enable standard Ram Air foam air filters to be fitted onto either ITBs or Carburetors. Designed with a 25mm insert and an external length of 100mm, these trumpets taper from 50mm to 45mm over the full 125mm length. Two-millimeter thick walls provide rigidity, while the insert features relief cuts for a snug fit and a ridge that sits against the ITB/Carb for stability. Best printed in ABS or PETG for automotive use, two styles are available: 1 x Standard Trumpet 1 x Standard Trumpet with mount for a Mass Airflow Sensor ("MAF") Installed and functioning on my Robin Hood 2B, which runs a 1600 Sigma engine on converted Dellorto 40's to ITBs.
