Haven't posted in awhile, but have still been browsing. I was wondering is someone known the size and thread count of the drain plug for the Koyo radiator R1443? Thanks.

 

Same as the stock one iirc....

In case it isn't...

Are brand new drain plugs available for my Koyorad All Aluminum Racing Radiator? Where can I purchase one?

Yes. Brand new Koyorad drain plugs (Koyo part# PI1186) can be purchased through the Koyorad retailer who sells Koyorad Race Radiators. For reference, our Koyorad drain plugs are sized M10 x P1.25.


Google for the win


I think I bought one here once upon a time: http://www.good-win-racing.com/Mazda.../61-0537b.html

 

I don't believe in Google. I use Ask Jeeves.


I mean thanks.
