I'm in between either a aluminum radiator or intake manifold which should I get first? Really need help here

Hi.Depending what your main aim is bud. Cooling is essential in any engine. So if you are looking to upgrade performance over a period of time, I will recommend you go the Ellie radiator first.

I say radiator. Regardless of your endgame, you will need to replace the stock radiator because of age. It is inevitable.

I have the Koyo. You will see a difference in coolant temps even when using the stock thermostat. I don't think it's enough for a performance gain tho. Maybe 5 degrees if you monitor it digitally. But that's good over the long term. For engine components and oil life

replacing the radiator with an aluminum multi row would be a very good thing to do especially considering age of our vehicles. however,to obtain full capability of it and do the most benefit to the engine, youll probably want to do a low tempt thermostat as well and depending on when it was done, do a new water pump. remember, when installing the new radiator, ensure you complete a full system flush prior to install of the new system. I would recommend while you have the radiator out, remove the thermostat as well and using distilled water and a funnel and some sort of pressure system (a pull and push squirt gun works well) push distilled water through your colling/heater core system until all contaminants are removed.

its time consuming, but worth it. as well, use a newer style quality coolant fluid.
