Hi,
Can you help me to find a new radiator on the net for my 99 F4? Im searching now for a while and didnt find any. Please help me.

 

You say new so 19010-MBW-671 is the partnumber and Service Honda is going to be the best price at $357 + shipping. You could prob find a used one on ebay or from someone parting out but you need to browse the classifieds section and put up a want add. Beware that the over flow niple likes to break off these so ask about it before buying used.

 

Will a F4i radiator fit into my F4?

 

Yes
