koyo are all aluminum stock replacement..... stock has plastic end tanks and aluminum fins. if thats what you ment.

 

how hot does your coolant get? is it a noticable difference? or did you do it for precaution?

 

right on, maybe you could help me in the future hahahaah....how many miles..just wondering why your radiator started to leak....

 

about 56,000 miles........ i know thats a lot its actally from seattle(mainland vehicle). you usually spot it right under/around the upper radiator hose, it has a coolant residue on the radiator plastic end tanks. if you see the residue the upper/lower hoses are also probably leaking thru the threaded part of the hoses(you will see it once take off the hoses). soo ya..... know i am also trying to shoot for a new clutch also.......i think i might go with a STI clutch.... got any suggestions anyone?< i know its the wrong place to ask.

 

i dont really think it really does much, but it holds a lot more(as in capacity wise) coolant running thru the engine. but i would recommend this radiator also with get the hoses too!.... it looks great. well i did it cuz i saw coolant leaking(coolant crust) around the hoses and the top of the radiator. so i rather do it now then or get stranded on the freeway and risk blowing a head gasket(s) and/or warping the heads or even a block...... that would really suck! i have seen that happen, so i was hoping everyone would read this so they can take care there prized possesion, cuz we all know about the whole glass trans.... and making us(WRX owners....... yes i've got owned before) stranded on the road. cooling system is very important >preventive maintance! hope this really opens peoples eyes. pretty much my two cents :banana:

 

here more pics how tight it is!

 

its kinda hard to take pics of it cuz my camera isnt small enough to get closer picture hopefully it helps. :banana:
