Time for a cooling system refresh - OEM radiator still the way to go?

[D-O]

I've had the same experience with the koyo on a street/track/fun car in the south. I'm even running one of those junk metal impeller water pumps. Regardless, you will never drive your car hard enough in hot enough weather to convince the OE only folks.

Edit: almost the exact same use case based on location. Haha.

Seems like we are neighbors!

I would have gone OE myself, but they were not available at the time I needed it. If the OE becomes unobtanium its worthwhile to know what the viable alternatives are.

Koyorad Update:

No problems with cooling at Road Atlanta this past weekend. Alternator gave up the ghost, but no cooling problems.

Thats great! Would have loved to get one but i dont see FCP or ECS shipping it to Bahrain or even carrying them LOL

Were you also at the Jzilla event? I had issues with my cooling system and a OE rad, finalizing my decision on getting a Koyo. I had a spare alternator with me at the track

Yes, Jzilla event at Road Atlanta. I am local, so after a tow home I put in a spare and made it back for Sunday.

Long way from Houston....

koyorad is 2 pass just like OEM. I thought about trying it but was tired of dicking around with it so went to OEM. I like the two pass design for folks that still have AC. The condensor blocks too much airflow for triple pass to work IMO.

Yea, I come at least once a year for Summer of Esses. I try and do the September event as well. I have a close friend in Atlanta, and it's an amazing track so well worth the commute. My wife and I drove up in the M3. Hopefully we can connect next time at a Jzilla event or when I am in town.

Right on.

Update question - is this the OE referred to? Over $700 on FCP: https://www.fcpeuro.com/products/bmw...em-17102228941

Yeah that's the one.

I'm a big OE purist, but I went with the do88 radiator for a little less money and honestly consider it an upgrade.

Not much of a discount. MSRP is ~$750. Your can get it cheaper elsewhere.

The current OE rad is unbranded and the OEM Modine rad was replaced with NRF according to previous posts.
