Std 325i preface throttle body size?

Post Sun Nov 22, 2020 6:42 pm

Hi, I removed my 1987 325i Sport throttle body and measured it. It's 63.5mm. Is that bigger than standard?
I've seen a big bore version on eBay, its diameter is stated as 64mm?

they are 60mm @ the butterfly noting that it is tapered meaning the entry is larger like 63mm or thereabouts
