Here is a used genuine Porsche throttle body 047.133.063 as used on certain 1976-85 924 models.
I've had this refurbished and with performance upgrade.
Ported and Polished Throttle body. This throttle body will improve airflow which will increase performance. The ports measure inner diameter of 37mm.
This Throttle body is Highly Polished inside, I like to say its AS SMOOTH AS A BABIES BOTTOM.
This appears to be a stamped above the base unit judging by the size of the 35mm primary butterfly.
The unique numbers are B9 33 724/1 stamped onto the housing.
This would also fit MK1 Golf/Jetta/Scirocco GTI 1.6/1.8 as the only difference are the linkage which can be swapped for compatibility.
