I can’t recall which throttle body I have on my 4.6 motor, but its from a later v8 and just needs the plug to be wired into the loom. I’ll see if I can find which car it came from, it in my notes…just in case yours fails it may be plug and play. I don’t really notice any difference, other than maybe a better intake sound on acceleration, but my OE throttle failed and my Indy recommended this one. Been 2 or 3 years and it’s working fine.

Edit….I seem to recall it being 84mm and from the N62 powered 540i. RealOEM has the part number as 13547535308

Thanks a bunch, @Henn28. Appreciate all the replies, too. You the man!

Below is URL to DINAN TB for E53 / V8 models of the period (of course it's NLA):

According to their site --- The throttle body is 3mm larger for an 8% increase in airflow area (Stock bore 79.5mm; Dinan bore 82.5mm).

• Improved throttle response

I do have the OE TB that I'll travel with, just in case.
