When i get my crx out of the shop from being turbod wich radiator should i use, a factory si one or an automatic radiator [ automatic one is bigger ] i have been using the bigger one since mid-winter

 

Probably neither of those. Go get yourself an EG rad.

 

if it fit use it cause you wouldnt want any over heating problems but i think the auto is thicker cause it has tranny cooler in it
