Product fits great, have to use longer throttle body bolts from ARP. Gives a nice throttle response and feel more torque.
I don't know Extension doesn't fit for my car. I will be custom fabricating one.
This product is listed as fitting only: • 1999-2004 Ford Mustang GT 4.6L V8 • 2001 Ford Mustang GT Bullitt 4.6L V8
