Engine radiator OEM BMW or KOYORAD
The radiator you could go OEM or NVA, but Koyorad is proven solid also.
Pros: proven solid
Vehicle:
Nissan
For your turbo Baja, [Koyorad](https://ebay.us/m/yadARd) is the creme de la creme.
Pros: creme de la creme
Vehicle:
Subaru
I went with a Koyorad radiator from rock auto and then I also replaced the inlet and outlet hoses with OE. A new OE radiator cap, too. Subarus are fairly sensitive to cooling system parts, so for any mechanical bits (cap, water pump, thermostat, etc) I highly recommend spending on OE.
Pros: highly recommend spending on OE
Vehicle:
Subaru Forester
Just dealt with the same thing with my AP1. The plastic to metal seam fails eventually and causes the leak. I got the Koyorad OE replacement and it was around $100 and took an hour to install.
Pros: OE replacement
Cons: plastic to metal seam fails
Vehicle:
Honda S2000
Koyorad if you want good OEM fitment and a fucking drain bung plus good cooling even for modified engines (we’ve put a bunch of the larger alloy ones into rx7’s)
Pros: good OEM fitment, good cooling
Cons: price higher than Fenix
2004 E46 320i manual with 116k miles. Bought it just over a year ago for \u00a32000 probably spent around \u00a31000 on it (radiator, air con, rocker cover gasket, oil sensor, boot switch, coil pack), not too bad for a 20 year old car I don\u2019t think. Only thing that doesn\u2019t work on it is the cruise control, it used to but recently stopped.
Pros: not too bad
Cons: cruise control stopped
Vehicle:
BMW
Mileage: 116000 km
im steady at 75°C (167°F) with stock Ka, koyorad radiator, fanshroud and oe/oestyled clutch fan. and iirc, a stock nissan thermostat. hottest ive seen was like 89°C (192°F) and that was sitting in traffic on a hot summer day. idk how im running so cold lol.
Pros: steady at 75°C, runs very cold
Vehicle:
Nissan
I went with a Koyorad, but for how much I’ve spent, I should have gone with a crossflow (either Supermiata or Flyin Miata). I also did a coolant reroute, which made me really regret not getting a crossflow
Cons: regret not getting crossflow, perceived poor value
bmw makes a sad excuse of a cooling system with brittle plastic, sad plastic joins and a pathetic plastic and metal radiator, like that's gonna last
Cons: brittle plastic, sad joins, pathetic radiator
During Covid a lot of brand new genuine BMW parts had some issues so I had to change my radiator twice, was covered by BMW dealer after loads of back and forth. (There’s two part numbers for B48 engine main radiators and the dealer said the part number used was not meant for the car but the other radiator clearly wouldn’t fit)
Cons: parts had issues, changed twice
Vehicle:
BMW
