I found some very nice full kits (reasonable compared to OE rubber) but
long term piece of mind – especially for the rad hoses. Not so much for the
turbo plumbing as it is just passing air. Also doing a base line restoration,
it is good to throw out all the small diameter vacuum lines and start fresh.
They are blingy – available in blue/red/black.
They do not offer anything for the B280F (V6). I will keep looking.
