I bought a CSF JDM Radiator from Manny at TBK Performance in Miami. It was pretty reasonable. Ask him where he got it. It's definitely cheaper than the corksport.
I have a CSF now from radiator express. it was 145 (i use a pro5 one), but im getting a hookup on the corksport one so itll be wiser to get that one. plus its purdy. Thanks for the tip though, if all goes bad and i cant ge tthe CS one ill ask manny
