MS6 Radiator Replacement

Alright guys so as you know I have probably replaced 80% of my car at this point lol Anyway my radiator has slowly developed a leak. The plastic bottom where the drain plug is, is the first culprit and the second is it slowly leaking out the seam where the core and the top section meet. It is nothing too bad but would like to replace this before winter.

I'm hoping someone has replaced a speed 6 radiator and if factory replacement is best or a a mishimoto or something like that.

 

I would get an aluminum one if it's available. You'll have less chance of a failure with that. If there is a dual pass option I would go for that.
