FD3S_wanted

Hi guys,

I broke the drain plug on my koyo radiator for an S4. I'm looking for a replacement. Do you know where I can find these? I have done all local part store and I was not able to find it. I have searched the forum and someone told that the stock S5/FD drain plug should fit but he didn't seem to be sure. Can someone confirm this?

Thanks

The used Koyo I bought for my FD came with no plug, so I used the one out of my stock radiator.

That was an FD radiator, though...give it a try anyway!

as far as I know, all koyo radiators re use all stock parts. so just try stock plugs

Do you know if s4 and s5 plugs are the same?

The drain plug on my koyo is m10x1.25, but its the u-flow model.

Not sure if s4 and s5's are the same.

a brass plug would be good, this plastic plug sucks

I just ordered 2 replacements, now I will keep track and after I remove it a few times im going to change it out

N326-15-203 does not fit my Koyo, I ordered one from Mazdatrix on Sunday and one picked one up from my local dealer today because I could not wait, they are too large!

I ended up with a 10x1.5mm bolt for now.

The new Koyos come with aluminum drain plugs (or at least mine did). But I haven't seen any place that will sell just the plug by itself.
