If anyone has any questions as to whether these radiators are absolute pieces of shit...dont wonder, they are. 18 months later and it leaking at the welds. $500 dollars later and Im back to a stocker. Im sending the old one back to Mishimoto, one way, with a note that their radiators blow. I wished I had listened to the ump-teen other people that said this before I bought one. Save yourself the trouble, get a Fluidyne or keep the stocker. Rant off.
