Throttle body difference 351W
1991 Bronco with 351W. What is the difference between the original throttle body F1TZ9E926Gon my 91 Bronco with 351w and the later F6TE-RA throttle body?

The coolant line fittings changed shape and it went from 2 evap connections to one.

Thanks. So if I replace the one on my 91 Bronco it shouldn't matter which one I get, correct?

If you get the single EVAP throttle body, plug 1 line on your EVAP.

No it won't matter, functionally they are the same and fwiw I believe the 5.0 use the exact same TB too.

Yes. Both engines use the same throttle body. I used to pick up spares when at the junkyard since the BBK t/b is expensive junk.
