Hose sizes?

[fieldl]

Don't suppose anyone knows the diameter of the following:
* Coolant hoses - there are few different I know
* Air intake - someone has bodged some crummy extension on mine

Thanks

Aha genius. Its for an 88 325 M20b25. Doh of course it would to help to know which engine wouldn't it.

Air intake, do you mean between the AFM and TB? if so that's under £20 from the dealer. Most hoses have T's and bends so will probably be dealer too.

There was a group buy for a silicone hose set for the M20. Might be worth a search.
