Oil Cooler

[F1Dryvr]

I know this has been beaten up a bit, but ive been running an OE cooler for years with a huge dent underneath it essentially starting to fold it in half. Its been great!!! Its time for a new one though and I know OE is often recommended but its only 100 more for csf. Hoping to get some replies here as a certain bmw store has a sale and would like to take advantage. CSF vs BW?? Ive read of issues with both. This is for a track only car and I already have a diverter valve.

Thanks!

From what I know stock parts perform better than aftermarket in certain cases. The stock oil cooler is good on its own. The CSF oil cooler will increase the oil capacity by another quart I believe.
