High performance aluminum radiator upgrade for Z4M

1zpower7 · 10-22-2022, 07:51 AM

Looking for high performance aluminum radiator upgrade for my Z4M roadster.
Recommended pair number by CSF or Mishimoto? (direct fit)

grannyknot · 10-22-2022, 08:12 AM

I bought the CSF rad for the Z4M about 5 yrs ago but I don't think they are still making them.

1zpower7 · 10-22-2022, 08:14 AM

Do you have CSF part number?

Zionsville do a very high quality piece but its not cheap.

Wow, pricey

Why the E46 M3 aluminum radiators won't fit the Z4M?!

No they don't fit, the Z4 rad is smaller.

I've contacted Mishimoto and they told me that this will fit my Z4M:

I've not yet sure which one of the CSF rads is compatible.

Seems Mishimoto is right, 2 different part numbers but interchangeable.
Sorry for the mix up.
Looking at that Amazon ad I would say that it is identical to the CSF rad that I bought, right down to the look of the welded on flanges, it may be there is one manufacture that made them for both Mishimoto and CSF but CSF has dropped the rad from their catalogue due to lack of sales.

I'll dig back in my old pics and see if I can turn up a pic of the CSF rad.

That's your firewall doing that. Or maybe your computer is forbidding you from modding your car?

That link is for the M54/52 e46. Peculiar in the description is says E46 Z4 but when you select or go to what cars it fits does not list the E85 and plugging info in says it does not fit the 03-05 Z4. Wonder if it does or doesn’t or if someone at ecs neglected to finish typing up full details. Anyone have this installed on their non M. I passed on the one mishimoto had because it still incorporates plastic for Non M.

I’ve been using the CSF 3055 on my track car Z4MC. It fits and functions fine. I did not use the factory oil cooler and suspect that this may be the issue with this radiator. Not sure it has the mounts for the under radiator oil cooler.

I am using the CSF 3055 and using the factory oil cooler. Fit is basically perfect... i just need to get one longer screw because the CSF rad is a bit thicker.

ctdriver86 · 06-13-2024, 11:01 AM

bumping this thread, I checked real oem and the part number also reference non-m e46. Has anyone used and can confirm a non-m full aluminum radiator fits with or without issue? I ran Koyo in my e46 m3 and have been happy and would like to use the koyo non-m full aluminum. Wanted to see if anyone has tried a non m radiator.

Thanks!

According to this post it should fit

It’s works perfectly… I have been running the CSF radiator in my Z4M since 2020.
