The original radiator was aluminum, with plastic tanks. It cracked lengthwise along the top tank. As it turns out, that is a common thing. The normally black plastic (on those particular radiators) first turns brown, and then green. Once green, it is in danger of literally falling apart.
Having said that, modern aluminum radiators are far more efficient than my 50 year old radiator. Modern radiators have wider tubes and are thinner enabling better airflow and heat transfer. Aluminum is lighter and stronger than brass-copper. Both will work, especially if your car is stock.
I am choosing between the koyo oem replacement for 160 $ and the koyo 350 dollar upgraded aluminum radiator. This car is 95 % typical daily driver with some fun driving but not much. The car has cat less 3" exhaust from down pipe back, cai, upgraded blow off valve, and a lightweight flywheel. The motor is a Jdm ej207 sti swapped into an 04 wrx.
Copper fins transfer heat faster than aluminum, but aluminum is lighter and the welded feature may be stronger. The choice is yours but a high-quality radiator of either material should do the job.
Do aluminum radiators have a better cooling effect? A copper brass radiator cools better than an aluminum radiator. A copper brass radiator with 5 rows of 1/2″ tubes, for example, is equivalent to an aluminum radiator with 2 rows of 1″ tubes. Aluminum has a higher efficiency, is light, and has a longer lifespan than copper brass.
For example, a 480mm radiator can hold four 120mm fans, while a 280mm radiator can have two 140mm fans attached. You will need to check what fan mounts your case has and go from there. It's also
An aluminum radiator will cool a lot better than a copper brass radiator. As an example an aluminum radiator with 2 rows of 1″ tubes has the same cooling capacity as a copper/brass radiator with 5 rows of 1/2″ tubes. An aluminum radiator provides high efficiency, is much lighter, and has a equal life expectancy compared to copper/brass
good review. i would assume the more expensive, triple pass radiators would cool better than the cheaper single pass radiators. however, unless im reading it wrong it doesnt seem to be an "apples to apples" comparison. the champion had medium profile fans but then you changed to extreme duty fans on the other 2 radiators that you said doubled the cfm.
