Originally a custom design for a customer, this throttle body adaptor was made to fit his supercharged 7.3 in his XB coupe.
It should fit any oval throttle body Whipple supercharger and will provide 20 degree angle down and ~21.6 extension at the lower side.
Machined from 5083 aluminium, and available in raw machined finish only at this stage (individual anodising is available, but will cost ~$90 extra due to my anodisers minimum charge.)
